Question c) please a) The distance, r, between the proton and electron in the hydrogen atom is about 10¬10 m.i) Calculate the electrostatic force between the electron and proton.ii) Determine the value of the potential energy U of the electron in the hydrogen atom.Express your result in electron-volts (eV). Recall 1 eV = 1.6 × 10-19 J.ii) Determine the value of the kinetic energy of the electron. Express your result in eV.b) A small rectangular coil of 6 mm by 6 mm is placed in the middle of a solenoid of 40 mmlength 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 therectangular coil due to the magnetic field of the solenoid given that a current of 2.0 A ispassed through the small coil. Take vacuum permeability µo = 4x × 10-7 H/m.c) A circular metallic disc is placed with its plane perpendicular to a uniform magnetic field offlux density B. The disc has a radius of 0.2 m and is rotated at 5 revolutions per secondabout an axis through its center perpendicular to its plane. The e.m.f between the centerand the rim of the disc is balanced by the potential difference across a 10 N resistor whencarrying a current of 1 mA. Calculate the magnitude of the magnetic field strength.
