A point charge +q is fixed at a distance a from an infinite, grounded conducting plane, then induced charge on the plane is
In some charging process, a body acquires net positive charge then the mass of body.
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.
A positive charge is placed inside a positively charged spherical shell then
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.
When a charged body is brought near an uncharged conductor on the insulating stand
The correct answer is: The nearer end of the conductor acquires opposite charge and the farther end the same charge
How many electron are there in one coulomb of negative charge?
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
Which of the following process in which charge is conserved?
The correct answer is: All of the above
Charge produced on a metal sphere in induction process is due to
The correct answer is: Alignment of charge
