The three charges each of 5x10 coulomb wre placed at verter of an
equilateral triangle of side ro.coo. The force esented on the change of
1 re placed at centre of tringle is Newton will be-​

Answer 1

3 point charges of +Q are placed on an equilateral triangle. They will repel each other and go away from each other and go away from each other. So, the charge which we want to keep in the center should be negatively charged.

Let us consider the charge at center be −q. Let the length of side of equilateral triangle is a. Consider an equilateral triangle ABC, with centroid at D.
