The peak-hold circuit shown below was built using some unknown values of R1 and C1. When you applied a sine input, you observed a time constant of 2 ms. You further observed that when you connected a 30 kΩ resistance in parallel with R1, the time constant reduced by a factor of 3. Answer the following questions. What is the value of R1? Enter your answer in kΩ
