and inversely proportional to the square of the distance between them.
What is the force between two charges?
Coulomb’s law, or Coulomb’s inverse-square law, is an experimental law of physics that quantifies the amount of force between two stationary, electrically charged particles. The electric force between charged bodies at rest is conventionally called

What is force per unit charge?
Answer:
Electric Field
. Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge.
The
force acts along the line joining the centers of the spheres
. Because the same type of charge is on each sphere, the force is repulsive. As expected, the force between the charges is greater when they are 3.0 cm apart than when they are 5.0 cm apart.
How is the force between two charges affected when each charge is doubled and distance between them is also doubled?
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.
What is meant by electric force?
The attractive or repulsive interaction between any two charged objects
is an electric force. Like any force, its effect upon objects is described by Newton’s laws of motion. The electric force – F

How will the force between two charged spheres be changed if the distance between the spheres centers is reduced to half its original value?
Explanation: The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if distance between charges is halved (charges remaining kept constant),
the force between the two charges is quadrupled
.

How is Coulomb’s law derived from Gauss law?
To derive Coulomb’s Law from gauss law or to find the intensity of electric field due to a point charge +q at any point in space using Gauss’s law ,
draw a Gaussian sphere of radius r at the centre of which charge +q is located

Who explain the law of gravity?
Isaac Newton
put forward the law in 1687 and used it to explain the observed motions of the planets and their moons, which had been reduced to mathematical form by Johannes Kepler early in the 17th century. …

What happens when two charged conducting spheres touch?
When the two conducting spheres are brought together to touch, it is as though
they become one single big conductor and the total charge of the two spheres spreads out across the whole surface of the touching spheres
. When the spheres are moved apart again, each one is left with half of the total original charge.
What is the force of gravity on the sphere?
The gravitational force on an object
within a hollow spherical shell is zero
. The gravitational force on an object within a uniform spherical mass is linearly proportional to its distance from the sphere’s center of mass (COM).
Solution by consideration. If we electrically connect two balls, the charge on the balls would redistribute, so the potential on the
both balls is the same
. The potential on the ball is the same as the point charge potential. It is directly proportional to the charge and inversely proportional to the ball radius.
What type of force is an electric field?
Electric fields and magnetic fields are both manifestations of
the electromagnetic force
, one of the four fundamental forces (or interactions) of nature.

Is the force the same for both spheres or different?
In the case of gravity near the earths surface, the force on an object that has a mass “m” is “mg”, that is, the mass of the object times the constant “g”. … Because the metal spheres in your problem are the same size and shape, the air resistance force on
them will be the same
(if they are falling at the same speed).
What is the relation between electric field and electric potential?
The relationship between potential and field (E) is a differential: electric field is
the gradient of potential (V) in the x direction
. This can be represented as: Ex=−dVdx E x = − dV dx . Thus, as the test charge is moved in the x direction, the rate of the its change in potential is the value of the electric field.
What is the force that exists between two charged bodies?
The force between two charge bodies is known as
electrostatic force
.
What kind of force is an electrostatic force short answer?
Electrostatic forces are
non-contact forces
; they pull or push on objects without touching them. Rubbing some materials together can result in something called ‘charge’ being moved from one surface to the other.
