1. The problem statement, all variables and given/known data The drawing shows three point charges fixed in place. The charge at the coordinate origin has a? q1 = +8.50 µC; the other two have identical magnitudes, but opposite signs: q2 = -5.00 µC and q3 = +5.00 µC. http://img66.imageshack.us/my.php?image=p1818mv9.gif (a) Determine the net force (magnitude and direction) exerted on q1 by the other two charges. (b) If q1 had a mass of 1.50 g and it were free to move what would be its acceleration? 2. Relevant equations F12=k|q1||q2|/r2 F13=k|q1||q2|/r2 3. The attempt at a solution F12= +2.128*1023 F13= -+2.128*1023 cos(23°)= Fx/+2.13*10^23 Fx= 1.96*1023 cos(23°)= Fy/-2.13*10^23 Fy= -1.77 *1046 Before I go any further, I wanted to make sure I am doing this right since I am kind of rusty. If anyone could check, it would be greatly appreciated. Thanks in advance!
