What is the surface charge density on the first sphere

Reference no: EM13316006

Two spheres with uniform surface charge density, first with a radius of 7.0cm and the second with a radius of 4.8cm , are separated by a center-to-center distance of 33 cm. The spheres have a combined charge of +55%u03BCC and repel one another with a force of 0.68N . Assume q1>q2.

What is the surface charge density on the first sphere? (c/m^2)
