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,a). the elementary charge of an electron is given by q = -1.602 x 10^-19 c.
a) determine the y-coordinate a of the third charge
b) determine the electric field at the centre of the equilateral triangle
c) determine the torque that acts on the dipole and the work done to align the dipole depicted in the picture the center of the equilateral triangle with the resulting field at the corner. the dipole exhibits a dipole
