Can you please answer this question by details
a.) A solid conducting sphere of radius 20 cm carries an electric charge of 5 µC.
Use Gauss's Law to find the expression for its electric field as a function of
distance from the center of the sphere for the case of radii larger than 20 cm.
Use this to find the magnitude of the electric field at a distance of 50 cm from
the center of the sphere.
b.) A thin straight piece of wire carries an electrical current of 5 A. Use Ampere's
Law to find the expression for the magnitude of the magnetic field around the
wire and evaluate the magnitude of the field at a distance of 10 cm from the
wire, assuming that the wire has a radius of 2 mm.
