A uniform magnetic field and a uniform electric field are produced, pointing in the same direction. An electron is projected with its velocity pointed in the same direction. What will be the effect on electron?

Text Solution

Verified by Experts

The electron velocity will decrease as it will experience force due to electric field opposite to the direction of electric field but no force will be acting on electron due to magnetic field.
