Exam I had an average of 7.5, a standard deviation of A fine performance.

2. HITT
A parallel-plate capacitor has a plate area of 0.3m2 and a plate separation of 0.1mm. If the charge on each plate has a magnitude of 5x10-6 C then the force exerted by one plate on the other has a magnitude of about:
A. 0 B. 5N C. 9N D. 1 x104 N E. 9 x 105 N B

3. HITT2
Each of the four capacitors shown is 500 μF. The voltmeter reads 1000V. The magnitude of the charge, in coulombs, on each capacitor plate is:
A. 0.2 B. 0.5 C. 20 D. 50 E. none of these B
