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
- directed perpendicular to the plane of paper
- zero
- directed along OP
- directed along PO
Correct answer: zero
Solution
A stationary charge does not experience any force in a magnetic field because magnetic forces act only on moving charges. Hence, the force on the charge Q is zero.
