1. Two small conducting and identical sphere A and B have charges -25uC and +1SuC , respectively. They are separated by a distance of 0.02m. (a) What is the magnitude of the electric force between the two sphere? Is this force attractive or repulsive? 2. Compute the individual values and the total values of the capacitance, charge, and voltage of the circuit shown below. Given that the C = 6.31 x 10 -12 F, C, = 3.75 x 10 -12 F, C; = 7.23 x 10 -12 F and the voltage is 1400 V. C1 C2 C3 3.
