KCET2021PhysicsMagnetic Effects of Current
A strong magnetic field is applied on a stationary electron. Then, the electron
Options
- Amoves in the direction of the field
- Bmoves in an opposite direction of the field
- Cremains stationary
- Dstarts spinning
Correct answer
C. remains stationary
Step-by-step solution
Force on an electron in an uniform magnetic field is given as F=q v B Since, the particle is stationary, i.e., v=0 F=0 So, the electron remains stationary.
