If contact force between 2 kg and 4 kg is f1 newton and between 4 kg and 6 kg is f2 newton, then find out (f1+f2).

Question

If contact force between 2 kg and 4 kg is f1 newton and between 4 kg and 6 kg is f2 newton, then find out (f1+f2). (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

Mass of system =2+4+6=12 kg Now, 24-12=12 a ⇒ a=1 m / s 2 System 2 kg 24-f1=2(a) f1=22 N System 6 kg f2-12=6(a) f2=18 N

Q. If contact force between $2 k g$ and $4 k g$ is $f_{1}$ newton and between $4 k g$ and $6 k g$ is $f_{2}$ newton, then find out $(f_{1} + f_{2})$ .
