2. Three identical electric charges, each 25 µC, are at the corners of an equilateraltriangle with lateral lengths of 82 mm. a) Calculate the electric force acting on one charge from the other two. b) Let us now assume that one charge is negative (−25 µC). What will be the total force(size and direction) of either positive charge? c) What is the strength and direction of the electric field in the center of the triangle in
