What is the electric charge and field?
The electric field is
an alteration of space caused by the presence of an electric charge
. The electric field mediates the electric force between a source charge and a test charge. The field is a vector; by definition, it points away from positive charges and toward negative charges.
Which is the hardest subject in class 12?
CBSE Class 12 results:
Economics and maths
have the highest failure rates. Since Maths and Economics have an element of statistical ability, experts think it is not surprising that they have high failure rates in CBSE Class 12 board exam.

What is called electric field?
electric field,
an electric property associated with each point in space when charge is present in any form
. … The electric field may be thought of as the force per unit positive charge that would be exerted before the field is disturbed by the presence of the test charge.
What is Q in electric field?
The symbol q in the equation is the
quantity of charge on the test charge
(not the source charge). … Electric field is the force per quantity of charge on the test charge. The electric field strength is not dependent upon the quantity of charge on the test charge.
What is the formula for electric field?
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. E has units of N/C. The magnitude of the electric field E created by a point charge Q is E=k|Q|r2 E = k | Q | r 2 , where r is the distance from Q.

Can electric charges be created?
Electric charge, which can be positive or negative, occurs in discrete natural units and is
neither created nor destroyed
. Electric charges are of two general types: positive and negative. Two objects that have an excess of one type of charge exert a force of repulsion on each other when relatively close together.
What is an electric field Class 10?
An electric field
always surrounds an electric charge, and exerts force on other charges in the field
, attracting or repelling them. Electric fields are created by electric charges or by time-varying magnetic fields, both are the demonstration of electromotive force (EMF).
What is an example of electric field?
Examples of electric fields include
the field produced in the dielectric of a parallel-plate capacitor
(which creates an electrostatic field) and the electromagnetic wave produced by a radio broadcast monopole antenna (which creates a time-varying field).
