QUESTION: 1

Charge is quantized. It is given by

Solution:
QUESTION: 2

A point charge +q is fixed at a distance a from an infinite, grounded conducting plane, then induced charge on the plane is

Solution:
QUESTION: 3

 In some charging process, a body acquires net positive charge then the mass of body.

Solution:

Since we know that charging of a body depends upon transfer of electrons. So, if a body becomes negatively charged it will gain electrons that is its mass will increase and if a body becomes positively charged it loses electrons hence its mass will decrease.

QUESTION: 4

Which of the following are quantized?

Solution:
QUESTION: 5

A positive charge is placed inside a positively charged spherical shell then

Solution:

The charge in a spherical shell is always on the outward surface. Inside the shell, there isn't any charge, so there won't be any attracttion or repulsion experienced by the positive charge placed inside the shell.

QUESTION: 6

When a charged body is brought near an uncharged conductor on the insulating stand

Solution:

The correct answer is: The nearer end of the conductor acquires opposite charge and the farther end the same charge

QUESTION: 7

How many electron are there in one coulomb of negative charge?

Solution:

Given that

Charge (Q) = 1 C

Electron (e) = 1.6x 10-19

Number of electron (n) = ?

Q= ne

1 C = n x 1.6x10-19 C

n = 1/(1.6x10-19)

n = 6.25 x 1018 electron

The correct answer is: 6.25 × 1018

QUESTION: 8

Which of the following process in which charge is conserved?

Solution:

The correct answer is: All of the above

QUESTION: 9

Charge produced on a metal sphere in induction process is due to

Solution:

The correct answer is: Alignment of charge
