A uniform electric field and a uniform m...

A uniform electric field and a uniform magnetic field are produced, pointed in the same direction. An electron is projected with its velocity pointing in the same direction. Then,

A

The electron will turn to its right

B

The electron will turn to its left

C

The electron velocity will increase in magnitude

D

The electron velocity will decrease in magnitude

Text Solution

Verified by Experts

The correct Answer is:
D
If `vecv || vecB , vecF_(B) =0`
And e move in opposite direction of `vecE`so velocity decreases.
