Question

suppose now you disconnect the electrostatic voltage source and then slowly separate the plates.

i.What will happen to V, the difference in potential between the plates, and E, the magnitude of the elelctric field between the plates?
1-V increases, E remains the same
2-V remains the same, E increases
3-both V and E decrease
4-V increases, E decreases
5-V decreases, E increases
6-V decreases, E remains the same
7-V remains the same, E decreases
8-both V and E remain the same
9-both V and E increase

ii. What will happen to Q, the charge on the plates, and C, the capacitance of the system?
1-Q remains the same, C increases
2-Q increases, C decreases
3-both Q and C remain the same
4-Q increases, C remains the same
5-both Q and C decrease
6-Q remains the same, C decreases
7-both Q and C increase
8-Q decreases, C remains the same
9-Q decreases, C increases

Explanation / Answer

i) ?V remains the same, E decreases

ii) both Q and C decrease
