ICS Part 2 Physics Chapter 12 Short Questions Preparation

Question # 1

Why do the electrons tend to go to region of high potential?

Ans 1: We know that the electrons are negatively charged particles.So,when they are put inside an electric field they tend to go the region of high potential from the region of low potential.

Question # 2

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 # 3

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 # 4

How can you identify that when plate of capacitor is positively charged?

Ans 1: For the identification of positively charged plate of a capacitor golf leaf electroscope is used,For this purpose the plate of capacitor is brought near the positively charged disc of electroscope.If the divergence of the gold leaves increase then the capacitor will be positively charged and vice versa.

Question # 5

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 # 6

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.

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

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 # 9

What is photoconductor?

Ans 1: A material which behaves as an insulator when it is in dark and becomes conductor when it is exposed to light is known as photoconductor.

Question # 10

State coulomb's law.

Ans 1: It states that the force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charge and inversely proportional to the square of the distance between them.
