When a charged particle moving with velocity `vec(V)` is subjected to a magnetic field of induction `vec(B)` the force on it is non-zero. This implies that:

Options

A. Angle between `vecV` and `vecB` is necessary `90^(@)`
B. Angle between `vecV` and `vecB` can have at value other than `90^(@)`
C. Angle between `vecV` and `vecB` can have at value other than zero and `180^(@)`
D. Angle between `vecV` and `vecB` is either zero or `180^(@)`

Answer

C

Explanation

F=q`(vecVxxvecB)`=avB sin0 n
"therefore when" `0=0^(@) or 0=180^(@)`,F=0
