A circular coil of 20 turns and radius 10 cm is placed in a uniform magnetic field of 0.10 T normal to the coil. If the current in the coil is 5.0 A, what is the (a) total torque on the coil, (b) total force on the coil, (c) 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^(-5) m^(2) and the free electron density in copper is given to be about 10^(29) m^(-3) )

(a). A body may sink in one liquid but float on another. Given examples. (b). It is easier to swi in sea water than in a river water. Why ? (c). A hollow ball has an internal diameter of 10 cm and external diameter of 12 cm. it is found that it floats on water. Find the density of the material of the ball (The volume of a sphere varies as the cube of the diameter).

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^(-5)m^(2) and the free electron density in copper is given to be about 10^(29)m^(-3)) .
