Question

A proton enters a magnetic field parallel to the direction of the field. Then, the path followed by it is

A

circular

B

Straight line

C

hyperbola

D

helical.

Answer

Straight line

Explanation

Solution

As F = q $v$ B sin 0 we find in this case $\theta$ = O $\therefore$ F = 0
Thus, no deflecting force acts on the proton, so it follows the straight line path
