Capacitance is a measure of ability of capacitor to store charge.

Question # 4

Define electric polarization and electric dipole.

Ans 1: When dielectric is placed between the plants of capacitor,positive and negative charge of its molecules displace from their position.Positive charges are attracted towards negative plates and negative charges towards positive plate,dipoles are formed.This process is called polarization.
Two equal and opposite charges separated by a small distance is called dipole.

Question # 5

Define electric flux.Write its SI units.

Ans 1: The number of the field lines passing through a certain element of area is known as electric flux through that area.Its SI units is Nm²C^-1.

Question # 6

Does the total flux depend upon the shape or geometry of the closed surface?

Ans 1: No,the total flux does not depend upon the shape or geometry of the closed surface,It depends upon medium and charge enclosed.

Ans 1: 1.Electric field line originate from positive charge and end om negative charges.
2.The tangent to a field line at any point gives the direction of the electric field intensity at the point.

Question # 8

Define xerography and photoconductor.

Ans 1: Xerograph is a photocopying process,It is taken from the Greek word "xeros" and "graphos" when mean dry writing.
Photoconductor is an insulator in the dark and becomes a conductor when exposed to light.

Question # 9

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 # 10

Do electrons tend to go region of high potential or low potential?

Ans 1: Electrons tend to go to a region of high potential from low potential because electrons are negatively charged.

Ans 1: The number of the field lines passing through a certain element of area is known as electric flux through that area.Its SI units is Nm²C^-1.

Question # 2

Define electric intensity and give its unit.

Ans 1: The electrostatic force per unit test charge,at a specific point in the electric field is called electric field intensity.Its unit is NC^-1.

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

Define electric potential and give its SI units.

Ans 1: The electric potential at any point in an electric field is equal to work done in bringing a unit positive charge from infinity to that point keeping it in equilibrium.Its SI unit is Volt (V).

Question # 5

Describe the force on positive charge when placed between parallel plates with opposite and equal charges.

Ans 1: When a positive point charge is placed between parallel plates with opposite but equal amount of charge ,then electric field intensity due to one plate is equal in magnitude but in same direction of the electric field intensity due to the other plate.So the value of resultant electric field intensity is non-zero.Hence the point charge will be accelerated towards negative plate.

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.
