Question

Charge is the property of matter due to which it produces and experiences electrical and magnetic effects.

Electric charge on a body is always an integral multiple of the smallest discrete value of charge. Magnitude of

charge on 1 electron is equal to 1.6 × 10–19 C. Charge is a scalar quantity. Charge on a particle is independent

of its speed.

(a) How many types of charges exist in nature? [1]

(b) What is the CGS unit of electric charge? [1]

(c) Charge can be created or destroyed (True/False) [1]

(d) Like charges _______ each other.​

Answer 2

A charge is the physical property of a matter about which it experiences a force when placed in the electromagnetic field. The following are the answers to the above question.

(a) There are two types of charges that exist in nature. One is a positive charge and the other is a negative charge. The Positive charge is +1.6×10^-19 C, and the negative charge is -1.6×10^-19 C.

(b) The CGS unit of charge is statcoulomb (esu).

(c) Charge can neither be created nor be destroyed. It can only be transferred from one body to another. Therefore, it is False.

(d) Like charges repel each other. Unlike charges attract each other.
