A moving electron enters a uniform and perpendicular magnetic field. Inside the magnetic field, the electron travels along :

A

straight line

B

parabola

C

circular

D

hyperbola

Text Solution

Verified by Experts

The correct Answer is:
C
circular
Explanation: `r=(mv)/(qB)` m is the mass and q is charge of electron, when projected perpendicular to a magnetic field. The electron moves in a circular path.
