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
`v to (i) , B to (-hatk)`
`vecF = q (vecv xx vecB) implies (hatf) = [hati xx (-hatk)]`.
