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

Always along a line of force

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

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

None of the above

(IIT-1979)

Solution

(b) Because $E$ points along the tangent to the lines of force. If initial velocity is zero, then due to the force, it always moves in the direction of $E$. Hence will always move on some lines of force.
