Question

four charged particles are placed so that each particle is at the corner of a square. the sides of the square are 15 cm. the charge at the upper left corner is +3.0 microcoulombs, the charge at the upper right corner is -6.0 microcoulombs, the charge at the lower left corner is -2.4 microcoulombs, and the charge at the lower right corner is -9.0 microcoulombs. what is the net electric force on the +3.0 micro coulombs charge? what is the net electric force on the -6.0 microcoulombs charge? What is the net electric froe on the -9.0 microcoulombs charge?.

Answer 1

Figure each of the three forces (kQQ/d^2), then add them as vectors.
