A very long straight wire carries a current I. At the instant when a charge `+Q` at point `P` has velocity `vecV`, as shown, the force on the charge is

A

Opposite to OX

B

Along OX

C

Opposite to OY

D

Along OY

Text Solution

Verified by Experts

The correct Answer is:
D
Magenetic field produced by wire at the location of charge is perpendicular to the paper inwards. Hence by applying Fleming's left hand rule, force is directed along OY.
