A ciruclar coil of 20 turns and radius 10cm is placed in a uniform magnetic field of 0.1T normal to the plane of the coil . If the current in the coil is 5.0A what is the average force on each electron in the coil due to the magnetic field ( The coil is made of copper wire of cross− sectional area 10−5m2 and the free electron density in copper is given to be about 1029m−3).
