Explanation / Answer

here,

for the equivalent capacitance

1/Ceq = 1/(1.13 + 2.99) + 1/4.57

Ceq = 2.17 uF

Now, for the charge on 4.57 uF

charge = 2.17 * 15.1

charge = 32.7 uC

the charge on 4.57 uF is 32.7 uC = 32.7 *10-6 C

charge on 1.13 uF = 32.7 *10^-6 * 1.13/(1.13 + 2.99)

charge on 1.13 uF = 8.97 *10-6 C

charge on 2.99 uF = 32.7 *10^-6 * 2.99/(1.13 + 2.99)

charge on 2.99 uF = 23.7 *10-6 C
