A homogeneous electric field $E$ and a uniform magnetic field $\mathop B\limits^ \to $ are pointing in the same direction. A proton is projected with its velocity parallel to $\mathop E\limits^ \to $. It will

A

Go on moving in the same direction with increasing velocity

B

Go on moving in the same direction with constant velocity

C

Turn to its right

D

Turn to its left

Solution
