calculate the force experinced by an electron when it enters a uniform magnetic field of strength 2 T with vleocity `0.2 xx 10^(8) m s^(-1)` at right angles to the field. What kind of motion will it have in the magnetic field ? (Charge of electron `1.6 xx 10^(-19)` coulomb.)

Text Solution

Verified by Experts

The correct Answer is:
`6.4 xx 10^(-6)` N; circular because magnetic force is always perpendicular to velocity
