Two masses of 10 kg and 20 kg respectively are connected by a massless spring as shown in figure. A force of 200 N acts on the 20 kg mass at the instant when the 10 kg mass has an acceleration of 12 ms⁻² towards right, the acceleration of the 20 kg mass at that instant is;
A
2 ms⁻²
B
4 ms⁻²
C
10 ms⁻²
D
20 ms⁻²
