Solve the all parts of given problem:

Problem: A capacitor of capacitance C = 3.5 Î¼F is initially uncharged. It is connected in series with a switch of negligible resistance, a resistor of resistance R = 15.5 kÎ©, and a battery which provides a potential difference of VB = 125 V.

Part I: Calculate the time constant for the circuit in seconds.

Part II: After a very long time after the switch has been closed, what is the voltage drop Vc across the capacitor in terms of Vb?

Part IV: Calculate the charge Q on the capacitor a very long time after the switch has been closed in C.

Part V: Calculate the current I a very long time after the switch has been closed in A.

Part VI: Calculate the time t after which the current through the resistor is one-third of its maximum value is s.

Part VII: Calculate the charge Q on the capacitor when the current in the resistor equals one third its maximum value in C.

I want you to clarify the physics in this above problem.
