Consider charges placed at the corners of a rectangle> Let k=8.98755 x 10x^9. Find the electric potential at point P due to the grouping of charges at the other corners of the rectangle. Answer in units of V.

Point P is at the left upper corner of the rectangle.

The charge at the right upper corner is 9microC and is .41 m away

The charge at the left bottom corner is -7microC and is .2 m away

The charge at the right bottom corner is -10microC and is .456179 m away(by taking the hypotenuse)
