ICS Part 2 Physics Chapter 12 Short Questions Preparation

Question # 1

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 # 2

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 # 3

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 # 4

If a point charge q of mass is released in a non-uniform electric field with field lines pointing in the same directions,will it make rectilinear motion?

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

Question # 5

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.

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

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 # 8

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 # 9

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 # 10

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

Ans 1: Gold leaf electroscope is used,To check the polarity,disc of positively charged electroscope is brought close to the capacitor plate.If the divergence of gold leaves increases;the plate is positively charged and vice versa.
