Question

in a magnetic field of 0.5 tesla an electron is moving perpendicular to 6m per sec for acting on it is the field velocity 3×10.

if you dont know then please skip this its important​

Answer 1

Answer:

Force acting=B*I*L

I=V/R=Bvl/R

substitute and remember B V and L must be mutually perpendicular always to get non zero force
