## Homework Statement

Point charges +4.70 and -4.70 are separated by distance 3.90mm, forming an electric dipole.

The charges are in a uniform electric field whose direction makes an angle 37.0 degrees with the line connecting the charges. What is the magnitude of this field if the torque exerted on the dipole has magnitude 7.00×10−9 Nm ?
