Two objects, separated by a distance of 5.99897 cm, attract each other with a force of 1.2x10-9 N. Determine the charge of each if q1 has twice the charge of q2.?

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?
