KCET Electric Charges and Fields Sample Questions

1. If the sizes of charged bodies are very small compared to the distances between them, we treat them as ____________.

1. Zero charges
2. Point charges
3. Single charge
4. No charges

Answer: (b) Point charges

Explanation: If the sizes of charged bodies are very small when compared to the distances between them, we treat them as point charges.

2. The force per unit charge is known as ____________.

1. Electric current
2. Electric potential
3. Electric field
4. Electric space

Answer: (c) Electric field

Explanation: The force per unit charge is known as the electric field.

3. State true or false: The total charge of the isolated system is NOT conserved.

1. True 
2. (b) False

Answer: (b) False

Explanation: According to the conservation of charges, the total charge of the isolated system is always conserved.

4. What is the dielectric constant of a metal?

1. -1
2. 0
3. 1
4. Infinite

Answer: (d) Infinite

Explanation: The dielectric constant of metals is infinite. The dielectric constant of metal is infinite, as the net electric field inside the metal is zero.

5. The quantisation of charge indicates that

1. Charge, which is a fraction of the charge on an electron, is not possible
2. A charge cannot be destroyed
3. Charge exists on particles
4. There exists a minimum permissible charge on a particle

Answer: (a) Charge, which is a fraction of the charge on an electron, is not possible

Explanation: The quantisation of charge means that when we express something that has some charge, we imply by that how many times the charge of electrons it has, as the entire charge is related to an electron.
