Question: 1. Two small conducting and identical sphere A and B have charges -25/C and +15/C, respectively. They are separated by a distance of 0.02m. (a)

1. Two small conducting and identical sphere A and B have charges -25/C and +15/C, 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 circuits shown below. Given that the (1 = 6.31 x 10-12 F, C2 = 3.75 x 10-12 F, C3 = 7.23 x 10-12 F and the voltage is 1400 V. C1 C2 C3 3. What is the electric current of a conductor given a voltage of 25 V and a resistance of 10 0? 4. A copper wire has a resistance of 15.0 ( at a temperature of 14"C. After a current pass through the windings, the resistance rose to 12. 50. To what temperature was the wire heated? 5. Find the equivalent resistance of the combination of resistors shown below
