(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two small plastic spheres, one charged to 17 nC and the other to -17 nC, are connected by a 25-mm long insulating rod. Suppose this dipole is placed in a uniform electric field with strength 7.4 x 10^5 N/C. What is the maximum possible torque on the dipole?

2. Relevant equations

t = qEL

3. The attempt at a solution

t = qEL

=(17 x 10^-9 C)(7.4 x 10^5 N/C)(2.5 x 10^-2 m)

=3.15 x 10 ^-4 J

This can't be right. Is torque measured in Joules? Can somebody please help me out with this problem?
