1. The problem statement, all variables and given/known data the question is A conducting sphere has a diameter of 10 centimeters. If you measure its voltage to be 3700 V, what is the charge in μC you have put on the sphere? 2. Relevant equations V=3700, D=0.1 m, V=kq/R 3. The attempt at a solution 3700= (8.987 * 10^9 * q)/.1 q=.041 microcoloumbs. but it says im wrong?? am i making a mistake someplace?
