I need the answer for all 4 parts

(20%) Problem 7: A bank of batteries, total emf e = 7.5 V, is connected with resistor R = 150 k{2, capacitor ' = 470 pF, and two-pole switch S as shown. The switch is initially set to point b so that the R resistor and capacitor are in series. The switch is left in this position for a sufficiently long time so that the a S capacitor is completely discharged. '0 b - Otheexpertta.com ~ & 25% Part (a) The switch is disconnected from point b and connected to point a. What will happen to the voltage across the capacitor? o . . .- Grade Summary () The voltage will increase as a linear function of time. ki Deductions 0% () The voltage will increase as an exponential function of time. Potential 100% (O The voltage will not change. St . - Submissions () The voltage will immediately rise to . Attempts remaining: 6 () The voltage will immediately drop to zero. (162 per attempt) () The voltage will drop as an exponential function of time, getalled view () The voltage will drop as a linear function of time. Submit Tint cdbacl I give up! Hints: ) fora 0%, deduction. Hints remaining: Feedback: . deduction per feedback. w & 25% Part (b) Calculate the time constant, 7 (in seconds), for this circuit. = & 25% Part () Determine an expression for the charge on the capacitor as a function of time, g(), in terms of parameters given in the original problem statement. = a 25% Part (d) Calculate the voltage drop across the capacitor (in volts) at time = 110 us after the switch is connected to point a.
