If magnetic field in space is `1Thati`, electric field is `10 N//Chati`, no gravitational field is present and a charged particle is released from rest from origin, it will

A

not move at all

B

move in circular path

C

move in a helical path

D

move on a straight line

Text Solution

Verified by Experts

The correct Answer is:
D

Electric field will exert force and particle will move along its direction. Since `vecV||vecB`, so no force due to magnetic field.
