In the circuit shown below, the op-amp is ideal and Zener voltage of the diode is 2.5 volts. At the input, unit step voltage is applied, i.e. vIN(t)=u(t) volts. Also, at t=0, the voltage across each of the capacitors is zero.
The time t, in milliseconds, at which the output voltage vOUT crosses -10 V is
Correct : c
