Two parallel beams of electrons are moving with small velocities (v << c), then there will be-
Text Solution
Verified by ExpertsThe correct answer is:
A
Due to electrostatic force, there will be repulsion between electron beams. Due to magnetic interaction electron beams will attract each other as they are moving in the same direction.
As the magnitude of electrostatic repulsion is more than magnetic attraction therefore there will be a net repulsion.
