b) A small rectangular coil of 6 mm by 6 mm is placed in the middle of a solenoid of 40 mm length having 100 turns and carrying a current of 3 A. The sides of the coil are perpen- dicular to the magnetic field lines of the solenoid. Calculate the force on each side of the rectangular coil due to the magnetic field of the solenoid given that a current of 2.0 A is passed through the small coil. Take vacuum permeability Ho = 4n x 10-7 H/m.

To form a helium atom, an alpha particle that contains two protons and two neutrons is fixed at one location, and two electrons are brought in from far away, one at a time. The first electron is placed at 0.6001010 m from the alpha particle and held there while the second electron is brought to 0.6001010 m from the alpha particle on the other side from the first electron.
