Question 1

An ideal parallel-plate capacitor having circular plates of diameter D that are a distance d apart stores energy U when it is connected across a fixed potential difference. If you want to triple the amount of energy stored in this capacitor by changing only the size of its plates, the diameter should be changed to
◦ 3D.
◦ 9D.
.
D.
.

Question 2

At a distance d from a point charge Q, the energy density in its electric field is u. If we double the charge, what is the energy density at the same point?
u
◦ 2u
◦ 4u
◦ 16u
◦ 8u
