## PHYS208 Fundamentals of Physics II

### Hint for Ch. 33, 31E

For the time dependence of the charge expressed in Eq. 33-21,
ignore the cosine factor (let it equal unity) and solve for R
such that *q* / *Q* = 0.99 at time *t* = 50 T.

### Hint for Ch. 33, 33P

Find the time for which *q*^{2}/2C = 1/2 (*Q*^{2}/2C)

### Hint for Ch. 33, 34P

The charge *q* after *N* cycles is found by substitution of
*t* = *NT* = *2 pi N* / *omega*
into Eq. 33-21.

### Hint for Ch. 33, 36P
