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
A
Zero
B
Directed along OP
C
Directed along PO
D
Directed perpendicular to the plane of paper
Answer
Zero
Explanation
Solution
: Magnetic field due to bar magnets exerts force on moving charges only. Since the charge is at rest, zero force acts on it.
