Q.1: When the distance between two charged

particles is halved, what becomes the Coulomb

force between them?

Ans : Coulomb force between them becomes four times

Q.2: What is the value of electric Field of curl?

Ans.: Zero.

Q.3: What is the unit of electric potential in S.I.?

Write definition.

Ans.: The S.I. unit of electric potential is J/C or V. It is defined as the work done for bringing a 1.C. chargefrom infinity to point in a electric field.

Q.4: Why the electric potential of earth considered

zero?

Ans.: Since earth is a very big conductor so due the

transferring of charge the potential of each does not change.

Q.5: What is the law of conservations of charge?

Explain with an example.

Ans.: In an isolated system charge can not be generated or destroyed. It is called conservation law of charge.

Example : When a glass rod is rubbed on silk

then positive charge acquired by glass rod is equal to negative charge acquired by silk.
