Question

Four point charges (two with q=2.50µC and two with q=-3.0µC) are situated at the corners of a square of a side 1.0m. Find the resultant force that the charge at A will experience due to charges at the corners of the square and it’s direction.

(this question had a diagram but the diagram looks like a square, qA is in the top left corner, qB is in the top right corner. -qC is in the bottom corner of left and -qD is in the bottom corner of right.)

Answer 1

$\vec F=\vec F_1+\vec F_2+\vec F_3,$

$F=5.3~mN.$
