Electrostatic and Capacitance A positive and a negative charge are initially 50 mm apart. When they are moved close together so that they are now only 10 mm apart, the force between them will be 5 times greater than before 25 times larger than before 10 times greater than before 5 times smaller than before 5 times greater than before 25 times larger than before 10 times greater than before 5 times smaller than before ANSWER DOWNLOAD EXAMIANS APP
