Let two concentric spheres O be uniformly charged. The radii of the two spheres are R1 and R2 respectively (R2>R1). The charge on the inside is q and the charge on the outside is Q .
a. Calculate the electric field strength at a point r at a distance r from the center of O (know R1 < r < R2)
b. Calculate the potential difference between the two spheres

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?
