Question

Two identical bar magnets are fixed with their centres at a distance

d

apart. A stationary charge

Q

is placed at

P

in between the gap of the two magnets at a distance

D

from the centre

O

as shown in the figure Two identical bar magnets are fixed with their centres at a distance d apart. A stationary charge Q is placed at P in

The force on the charge

Q

is

Quantrex Academy · Accepted Answer

Correct answer: A. zero

The force of attraction on Q by the north pole of first magnet is F . The force of attraction on the same charge by n the north pole of another magnet must be opposite to that of the first magnet. Thus, they concel the effect of one other and hence force on the charge Q is zero.
