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

Along ox

B

Opposite to oy

C

Along oy

D

Opposite to ox

Text Solution

Verified by Experts

The correct Answer is:
C
`vec(F)=q(vecv xx vecB)=qv B(hati xx (-hatk))=qvB hatj implies` force on the charge is along OY
