VC is the ideal voltmeter in the figure. Resistance of the resistor shown is R. Initially the switch is in position 2 when charging of the capacitor starts. Initially the capacitor was uncharged. The switch in circuit shifts automatically from 2 to 1 when VC>2V/3 and goes back to 2 from 1 when VC<V/3. The ideal voltmeter reads voltage across capacitor as plotted. What is the period T of the wave from in terms of R and C ?
