(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

What is the shortest time after which there would be no measurable charge on a 5.0 microfarad capacitor that is charged, then discharged across a 2000 ohm resistance.

a. 0.001 s

b. 0.5 s

c. 10 s

d. 3600 s

2. Relevant equations

3. The attempt at a solution

According to the time constant the charge on the capacitor should decrease by a factor of 1/e every 0.01 s according to my calculation.

I don't know how to answer the question though.
