Question

A copper wire has 11029 free electrons per cubic meter and cross-sectional area 2mm2 carries a current of 6A. Calculate the force acting on each electron if the wire is now placed in uniform magnetic field of flux density 0.1T perpendicularly.

Hint:
= sin =
where, drift velocity () =
∴= =3×10−24
