For the circuit of Example 25.6, take= 100 V, R 1 = 4.0 k, and R 2

For the circuit of Example 25.6, take ε = 100 V, R₁ = 4.0 kΩ, and R₂ = 6.0 kΩ, and assume the capacitor is initially uncharged. Find the capacitor voltage and the currents in both resistors
(a) just after the switch is closed,
(b) a long time after the switch is closed. Long after the switch is closed it’s re-opened. What are V_C, I₁, and I_2. 
(c) just after this switch opening,
(d) a long time later
