Finding magnitude and direction of net torque on a dipole

[ick84]

Homework Statement

For the dipole shown, the charges are ± 3.0 micro coulombs separated by a distance of 3.20 nm and oriented so that the theta is 35.0 degrees. If the electric field has a magnitude of 8000 N/C, find the magnitude and direction (clockwise/counterclockwise) of the net torque on the dipole about the same axis as before.

Homework Equations

F = qE
torque = Fl

The Attempt at a Solution

first i solved for F = (3.0E-6 C)(8000N/C) = 2.4E-2 N

then solved for l = (3.20nm)(sin35) = 1.84E-9

net torque = 2 * F * l ??

NVM i solved it...

T = Fl
T = qEl
