Thank you, i was able to the problem out.

dW is needed to take a charge from infinitely far away and distribute it even across the surface of the sphere thus increasing the radius by an infinitesimally small amount. Thus making W to make the sphere be the the sum of dW from 0 to R which answers my integration from where problem. Thank...

Homework Statement To assemble a uniformly charged sphere, assemble it like a snowball, layer by layer, each time bringing in an infinitesimal charge dq from far away and smearing it uniformly over the surface, thereby increasing the radius. How much work dW does it take to build up the radius...

I have attempted each problem, but am getting lost on just what to do to solve. If i could be pointed in the right direction on how i should go about each problem that would be nice. Attached are my attempts at problems 1-3. Homework Statement SEE ATTACHMENT The Attempt at a Solution See...
