Physics Question on Electric charges and fields
A charged particle is free to move in an electric field. It will travel
A
always along a line of 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 active angle with the line of force
D
None of the above
Answer
along a line of force, if its initial velocity is zero
Explanation
Solution
Because E point along the tangent to the lines of force. If initial velocity is zero, then due to the force, moves in the direction of E.
