Do magnetic lines of force represent lines of force along the entire length of which the force on a unit pole would have the same value? Explain your answer.

Question 2

Assume a device is designed to obtain a large potential difference by first charging a bank of capacitors connected in parallel and then activating a switch arrangement that in effect disconnects the capacitors from the charging source and from each other and reconnects them all in a series arrangement. The group of charged capacitors is then discharged in series. What is the maximum potential difference that can be obtained in this manner by using ten 500-F capacitors and an 800-V charging source?
1.500 V
2.8.00 kV
3.400 kV
4.800 V
5.0

Answer to Question 1

No. The force on a unit pole depends on the strength of the magnet producing the
magnetic field and on the distance from the magnet.
