Answer:
6N
Explanation:
the acceleration due to force 14 N=
We know by Newton's 2 nd Law
F=ma
Therefore, F/m =a
Total Mass=4 kg+2 kg+1 kg.
Force(F)=14 N,
By putting the values,
14/(4+2+1)
= 14/7
=2 m/s^2
the contact force between A and B is used to move the bodies B and C only as in the diagram given.
We know ,F=ma
Hence F=(2+1)2
F=3×2
=6 N
if u have any doubt ask in comment to me box.
