An electron enters a magnetic field at right angles to it, as shown in Fig. The direction of force acting on the electron will be

A

to the right

B

to the left.

C

out of the page.

D

into the page.

Text Solution

Verified by Experts

The correct Answer is:
d
The direction of force is perpendicular to the direction of magnetic field and current as given by Fleming’s left hand rule. Recall that the direction of current is taken opposite to the direction of motion of electrons. The force is therefore directed into the page.
