ICS Part 2 Physics Chapter 12 Short Questions Preparation

Question # 1

Distinguished between electric field and field intensity.

Ans 1: Electric Field: The space or region around the charge in which it exerts its electric force on other charges is called electric field.
Ans 2: Electric field intensity: At any point in electric field the force experienced by a point charge q is termed as electric or strength at that point.

Question # 2

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 # 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

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 # 5

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 # 6

Write down two difference between electric and gravitational force.

Ans 1: Differences:Electrical force is might be attractive as well as repulsive while the gravitational force is only attractive.Electrostatics force is medium dependent while the gravitational force is not.

Question # 7

What is meant by EEG and ERG?

Ans 1: Electroencephalography: is usually applied over human brain to check its abnormal behaviour by the use of electrical energy.For this electrodes are connected to the selected portion of the head and the corresponding response is seen graphically through the screen of a recording device.
Ans 2: Electrocardiography: records the voltage between points on human skin generated by the electrical process in the heart,It is made in running position providing information about hearts performance under stress.

Question # 8

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 # 9

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 # 10

Is it true that Gauss's law states that the total number of lines of forces crossing any closed surface in the outwards direction is proportional to the net positive charged enclosed within surface?

Ans 1: Yes the above statement is true,The total number of lines of force crossing any close surface in the outwards directions means electric flux.
