question 42

Multiple Choice

A certain capacitor has a capacitance of 5.0 $\mu$ F. After it is charged to 5 $\mu$ C and isolated, the plates are brought closer together so its capacitance becomes 10 $\mu$ F. The work done by the agent is about:

• A) 0
• B) 1.25 *10^-6 J
• C) -1.25 * 10^-6 J
• D) 8.3* 10^-7 J
• E) -8.3 * 10^-7 J
