A charged 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
As we learned
Direction of Electric field -
Due to Positive Charge electric field is always away from the charge.
-
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.
Option 1)
Always along a line of force
Option 2)
Along a line of force, if its initial velocity is zero
Option 3)
Along a line of force, if it has some initial velocity in the direction of an acute angle with the line of force
Option 4)
None of the above
