An electron moving towards the east enters a magnetic field directed towards the north. The force on the electron will be directed
A
to the right.
B
to the left.
C
out of the page.
D
into the page.
Text Solution
Verified by Experts
Answer is option (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.
