Question # 10

Describe the force or forces on a positive point charge when placed between parallel plate,with similar and equal charges.

Ans 1: When a positive point charge is placed between parallel plates with similar and equal charges,then the electric field intensity due to one plate is equal in magnitude but opposite in direction of electric intensity due to other plate.So the value of resultant electric field intensity E is zero,Hence the net force on the positive charge is zero,Thus is will remain at rest.

Question # 3

Define electrostatics and electric force,

Ans 1: Electrostatics: The branch of physics which deals with the study of stationary charges is called electrostatics.Electric force: The force which holds the negative and positive charges that make up atoms or molecule is called electric force.

Question # 4

Suggest a method 'shield' an apparatus from electric field even when it is to be kept in the region where electric field is present.

Ans 1: An apparatus will be shielded from electric field when it is kept inside the metallic box,so that the charge will only reside on the outer surface of the container.It is in accordance with Gauss law.

Question # 5
