I can't figure out what I am doing for nothing! Max Torque...Please Help!
Two small plastic spheres, one charged to 18.95 nC and the other to -18.95 nC, are connected by a 50-mm-long insulating rod. Suppose this dipole is placed a uniform electric field with strength 8.130×10^5 N/C. What are the maximum possible torque on the dipole?
r = 0.050m
q1 = 18.95 nC
q2 = -18.95 nC
E = 8.130 e^5
Torque = r*F(perpendicular)
F = K * q1 * q2 / r^2 = 0.00129N
Toqrue 1 = 0.00129 * (0.050/2) = 3.23 e^-5
Toqrue 2 = 0.00129 * (0.050/2) = 3.23 e^-5
T1 + T2 = 6.46 e^-5 N*m
Motion is clockwise around pivot in center...
Ahhh what am I doing wrong?
