Explanation / Answer

let the common voltage after connecting in parallel be V
let charge in C1 = Q = C1*10 = 140 C
as Q = CV and for both V is same, so, Q is proportional to C
so, charge in C2 = 2Q,
after the parallel connection, the charges will rearrange such that the final charge distribution is proportional to the ratio of their capacitances,
so,
a) charge on C1 = Q/3 = 140/3 = 4.7*10^-5C

charge on C2 = 2Q/3 = 140*2/3 = 9.3*10^-5 C

b) potential difference across each capacitor = 10/3 =3.3V
