A conducting sphere with radius R = 2.50 cm has a charge of 5.00*10 C spread uniformly across its surface. (a) (5 points) What is the electric potential due to this sphere for all radil r> R? (b) (10 polnts) A particle with a mass of 5.00 grams and charge 3*109 C radially approaches this charged sphere, If this particle began at infinity and stops at r= 2R, what was the particle's initial speed?
