For the circuit shown in the figure, determine the charge on each capacitor for the following. (Let R1 = 4 k?, R2 = 5 k?, and Vemf = 15 V.)

(a) switch S has been closed for a long time
Q1    =    
Q2    =    

(b) switch S has been open for a long time
Q1    =    
Q2    =    

heres the picture as well

a) Q1

((V1)/(V2))=((R1)/(R2)) Vemf=V1+V2

((V1)/(Vemf-V1))=((R1)/(R2))

V1=(4/5)(15-V1)= ((60)/5)-(4/5)V1

((9)/5)V1=((60)/5) V1=((60)/5)((5/(9)))= 6.66 V

q1=V1C1=6.66 V(0.000001)= 6.66×106 ohm

Let me know if you need help with Q2
