← Two small charged spheres repel with a force F. One sphere is given three times its charge, and the distance between the spheres is doubled. What is the new force?A small positive test charge lies on the line that joins a fixed +25 µC charge and a fixed +4 µC charge, which are 70 cm apart. The test charge feels no net force. How far is it from the larger charge? →
