Question

Three blocks a,b,c each of mass 4kg ,2kg ang 1 kg are are contact on an frictionless surface and force of 14n is on a block then find force between a and b

Answer 1

force = mass x acceleration

acceleration = 14/4+2+1 = 14/7 = 2

let a be a block and b and c be another block

the force acted by b on a depends on both b and c

and it is equal to = mass x acceleration = 3 x 2 = 6 N
