A voltmeter of resistance 150kilo Ohms is connected across a 50 micro F capacitor. If at time t= 0 the voltmeter reading is 20V. Find

a) charge on capacitor at time t=o

b) voltmeter reading after 10s

c) the time which must elapse after t = o before 95% of the energy stored has been dissipated

2. Relevant equations

Q=cv

E=1/2 cv^2

3. The attempt at a solution

a) I used Q = cv

b) I used V = (Vo)(e) - (t/RC) formula but not getting the correct answer

c) I tried a bunch of things but didn't even get close to the answer.

So can someone show me how to solve (b) and (c).

Thanks!
