A uniform electric field and a uniform magnetic field exist in a region in the same direction. An electron is projected with a velocity pointed in the same direction. Then the electron will be
Options:
Answer:
C
Solution:
As the electron is moving parallel to both the fields, so magnetic force does not affect the electron's motion. But electric forceacts opposite to the motion of the electron. Hence, the electron will not be deflected but its speed will decrease.
