Can anyone help me with these problems? Thank-you 1.) The point of fission, a nucleus with 92 protons is divided into two smaller spheres, each with 46 protons and a radius of 6.9 10-15 m. What is the repulsive force pushing these two spheres apart? I know that F=k(q1q2/r^2) I'm not sure what the charges are. Would it just be 46x46 orr... 2.) Three positive point charges of q1 = 4.5 nC, q2 = 6.0 nC, and q3 = 2.0 nC, respectively, are arranged in a triangle, as shown. Find the magnitude and direction of the electric force on the 6.0 nC charge. I did change the charges from nC to C, nC is a billionith of a columb correct? Do I have to find to F1,3 F2,3 F1,3? Just to find q2? Also since I have no angles how would i break it into x & y components?
