hey everyone, this is my first post at this physicsforums.com dealy. i have a take home exam and I'm havin a rough time with the way the prof worded this question:
Consider a sphere of radius R centered at Ro (Ro is a vector) and a constant vector c which specifies a point in the sphere, where the origin of these vectors is arbitrarily chosen somewhere in space.
A) find the following integral:
(double integral sign) da / |c - r |
where da is an infinitesimal outward area vector at r on the surface S of the sphere. Express your answer in terms of Ro and c .
...so that's it...i'm confused about the components of Ro and c and r...and whether or not i even need them to do the equation...if anyone could get me started (or even finished...hehe) that would be really appreciated! THANKS
