An electron moving with a uniform velocity along the positive `x`-direction enters a magnetic field directed along the positive `y`-direction. The force on the electron is directed along

A

Positive y-direction

B

Negative y-direction

C

Positive z-direction

D

Negative z-direction

Text Solution

Verified by Experts

The correct Answer is:
D
`v to (hati) , B to (hatj)`
`vecF = q (vecv xx vecB) implies (-hatk) = -(hati xx hatj)`
