Homework Help: Physics

Posted by Jonny on Wednesday, May 4, 2011 at 10:08am.

Three charges are arranged in an equilateral triangle with sides of 4 cm. The coordinates and corresponding charge values are as follows: +4q at (-2,0); +2q at (2,0); -q at (0,3.464). The elementary charge of an electron is given by q = -1.602 x 10^-19 C.

Determine the torque that acts on the dipole and the work done to align the dipole at the center of the equilateral triangle. The dipole exhibits a dipole moment of ||p|| = 8 x 10^-12 Cm and an orientation of (-j, +i)
