1) Two point charges experience a force of repulsion equal to 3 x 104 N when separated by 0.4m. If one of the charges is 5 x 104 C, what is the magnitude of the other charge? 2) A parallel-plate capacitor has capacitance C. If the area of the plates is doubled, while the separation between the plates is halved, the new Capacitance will be?
