Two spheres with uniform surface charge density, first with a radius of 7.1 cm and the second with a radius of 4.8 cm , are separated by a center-to-center distance of 33 cm. The spheres have a combined charge of +55μC and repel one another with a force of 0.62 N . Assume q1>q2.
What is the surface charge density on the first sphere?
What is the surface charge density on the second sphere?
