ICS Part 2 Physics Chapter 12 Short Questions Preparation

Question # 1

What is electric potential energy and electric potential difference?

Ans 1: Electric potential energy: The energy is acquired by unit positive charge in carrying it from one point to the other against the electric field keeping it in electrostatic equilibrium is called as electric potential energy,It is the energy stored in the charge 'q' because of its position in an electric field.It is measured in joules.
Ans 2: Electrical potential difference: The electric potential difference between two points is defined as the work done in carrying a unit a positive charge from one point to other point while keeping the charge in electrostatic equilibrium.

Question # 2

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 # 3

What depend on the slow or fast charging and discharging of a capacitor?

Ans 1: How fast or how slow the capacitor is charging or discharging depends upon the products of the resistance and the capacitance called time constant.Capacitor is charged or discharged rapidly when RC is small.

Question # 4

Define electron volt.

Ans 1: It is defined as The amount of energy acquired or lost by an electron when it is displaced across two points having potential difference of one volt.It is measure on electrons volts.

Question # 5

Give the statement of Gauss's law.

Ans 1: It states that the total electric flux through any closed surface is equal to 1/e_otimes the total charged encloses in it.

Question # 6

Write two properties of electric field.

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 # 7

What is strength of electric field inside a hollow charged sphere and why?

Ans 1: The strength of electric field inside a hollow charge is zero.inside a hollow charge sphere q=0.

Question # 8

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 # 9

A point charge move rectilinear path in an electric field.Explain.

Ans 1: If a point charge q of mass m is placed at any point in the field in the point,it will follow straight or rectilinear path along the field line due to repulsive force.

Question # 10

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.
