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` can have any value other than `0^(@)` to `180^(@)`
B. angle between `vecv and vecB` is either `0^(@)` to `180^(@)`
C. angle between `vecv and vecB` is neitherly `90^(@)`
D. angle between `vecv and vecB` can have any value other than `90^(@)`

Answer

A

Explanation

The force (F) acting on a charged particle moving with velocity v in a magnetic field is given by `F=qvB sin thetaIf theta=0,F=0`.Similarly, `If theta =180◦,F=0` But it is given that Fne0. This implies that the angle between v and B can have any value other than 0◦ and 180◦.
