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 |
The force on the charge Q is [AIPMT (M) 2010] |
A) zero
B) directed along OP
C) directed along PO
D) directed perpendicular to the plane of paper
Correct Answer: A
Solution :
[a] 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.You need to login to perform this action.
