Q. A homogenous electric field $\overrightarrow{E}$ and a uniform magnetic field $\overrightarrow{B}$ are pointing in the same direction. A proton is projected with its velocity parallel to $\overrightarrow{E}$. 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
