Acceleration of 10kg mass =12m/s²
Force=ma
F=10x12=120N will act .
Net force on 20kg mass will be :
200N-120 N=80N
a=F/m
=80/20
=4m/s²
∴ The acceleration of 20kg mass is 4m/s²
Acceleration of 10kg mass =12m/s²
Force=ma
F=10x12=120N will act .
Net force on 20kg mass will be :
200N-120 N=80N
a=F/m
=80/20
=4m/s²
∴ The acceleration of 20kg mass is 4m/s²

then net force on com=200N..
Now accelaration of com=200/(20+10)=200/30 m/s².
Now we acceleration of com = (20a+10×12)/(10+20)=(20a+10×12)/30
So, 200/30=(20a+10×12)/30
or, 200=20a+120
or, a=4m/s².
