A uniform electric field and a uniform magnetic field are acting along the sa,e direction in a certion region. If a electron is projected in the region such that its velocity is pointing along the direction of fields, then the electron

A

it will turn towards right of direction of motion

B

it will turn towards left of direction of motion

C

its velocity will decrease

D

its velocity will increase

Text Solution

Verified by Experts

The correct Answer is:
C
Magnetic field applied parallel to motion of electron exerts no force on it as `theta= 0`. Electric field opposes motion of electron which carries a negative charge
`:'` velocity of electron decreases.
