MCQ
What is the work done by the magnetic field on the moving charge?
- ✓No work is done by the magnetic field on the moving charge.
- BWork done will be maximum.
- CWork done will be minimum.
- DBoth $A$ and $B$
✓
Answer
Correct option: A.
No work is done by the magnetic field on the moving charge.
The magnetic force acts in such a way that the direction of the magnetic force and velocity are always perpendicular to each other. If force and velocity are perpendicular force and displacement are also perpendicular, thus $W = FS$ cos $q$, if $q = 90$, work done will be zero.
