A charge 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 some initial velocity in the direction of an acute angle with the line of force
D) None of the above
Assuming the charge is initially at rest and no other forces are acting on the particle then,
The force acting on the charge = qE, where, q is the charge and E is the magnitude of electric field.
The direction of the force will be in the direction of electric field if the charge is positive and vice-verse if the charge is negative.And it will travel along line of force.
