Question

three bodies p,q,r are identical on a frictionless table. what is the acceleration of blocks & net force on block p

Answer 1

the acceleration of blocks and net force on block p is gravitational force

Answer 2

Suppose the common acceleration=aTotal mass=m+m+m=3mThen, a=F3mNet force on P=F1=ma=m×F3m=F3Force applied on Q by P,F2=(m+m) a=2m×F3m=2F3Force applied on R by Q,F3=ma=m×F3m=F3
