First, determine the direction of the force on q1. Since one charge is negative and the other is positive, the charges will exert attractive forces on each other. Therefore, the electric force on q1 will be directed
toward the right
. Therefore, the electric force exerted on q1 is 1.5×10-6 N directed towards the right.
What is the direction of the net force on charge q?

What is the net force on the charge due to other charges?
The force between charges
Remember that force is a vector, so when more than one charge exerts a force on another charge, the net force on that charge is
the vector sum of the individual forces
.
What is the direction of the force on the test charge due to the two other charges?
The thing to keep in mind is that the force above is acting on the test charge Q, in
the positive radial direction
as defined by the original charge q. This means that because the charges are both positive and will repel one another, the force on the test charge points away from the original charge.
What determines the direction of the electric force between two charges?
The direction of the force vector depends on
the sign of the charges
. If the charges are the same, the force points away from the other charge. If the charges have different signs, the force points toward the other charge((Figure)).
What is the force acting on the charge?
The electrostatic force exerted by a point charge on a test charge at a distance r depends on the charge of both charges, as well as the distance between the two. The electric field E is defined to be
E=Fq E = F q
, where F is the Coulomb or electrostatic force exerted on a small positive test charge q.
Is the second charged object necessarily exerting a force on the first?
In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a
repulsive force
upon a second positively charged object. This repulsive force will push the two objects apart.
Why is Coulomb’s law important?
It signifies, the inverse square dependence of electric force. It can also be used to provide relatively simple derivations of Gauss’ law for general cases accurately. Finally, the vector form of Coulomb’s law is important as it
helps us specify the direction of electric fields due to charges
.
How is net force calculated?
Net force is the sum of all forces acting on an object. The net force can be calculated using Newton’s second law, which states that
F = ma
, where: F is the net force. m is the mass of the object.
How is net charge calculated?
Multiply the proportion charged by the number of each amino acid present in the protein
. Subtract the negative charge total from the positive charge total to get the net charge.
What happens when two negative charges are brought close together?
When two negatively charged objects are brought near each other,
a repulsive force is produced
. When two positively charged objects are brought near each other, a similar repulsive force is produced. … Since both leaves are negatively charged, they repel each other.
Can an electric field be zero?
There is no zero-field point
for a pair of equal-magnitude-but-opposite-sign charges. Electric field is zero in that point because the sum of electric field vectors have same intensity and direction, but are opposite. That point is halfway between two like charges.
Why do electric field lines go from positive to negative?
The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge. … As such, the lines are directed
away from positively charged source charges
and toward negatively charged source charges.
What happens to the force between two charged objects when you double the distance between them?
Like charges repel each other; unlike charges attract. … The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled,
the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value
.
Which is the direction of the net force on the charge at the lower left?
Since the forces are repulsive, the net force will be away from the center of the square. The charge on the bottom left will be expelled largely by the charge on the top right, which is a double positive charge. Therefore, the direction of the net force on the charge on the lower left is
South West
, as shown by B.
What are the similarities and differences between electric force and gravitational force?
| Similarities Differences | Both have fields Electric force can be both repulsive and attractive but gravity only attracts | Both have potential lines Electric force results from charge but gravitational force results from mass |
|---|
