A capacitor that is initially uncharged is connected in series with a resistor and a 200 V emf source with negligible internal resistance. Just after the circuit is completed, the current through the resistor is 0.850 mA and the time constant for the circuit is 6.00 s.

Part A- What is the resistance of the resistor?Express your answer with the appropriate units.

R=?????????

part B- What is the capacitance of the capacitor?Express your answer with the appropriate units.

C=?????????
