A charge particle is free to move in an electric field. It will travel

A

always along a line a force

B

along a line of force, if its initial velocity is zero

C

along a line of force, if it has same initial velocity in the direction of an acute angle with the line of force

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
B
Because E point along the tangent to the lines of force. If iniitial velocity is zero, then due to the force, moves in the direction on E.
