Question : 60 of 65

Marks: +1, -0

Two rigid bodies of mass

5 {kg}

and

4 {kg}

are at rest on a frictionless surface until acted upon by a force of

36 {N}

as shown in the figure. The contact force generated between the two bodies is

Solution:

As after action of

36 {N}

, both blocks will move with same acceleration so considering

5 {kg}

and 4 kq together in a system and applying Newton's 2 nd law.

a=\;{36}/{9}=4 {m}{/} {s}^{2}

N=m a \;\;

{Newton's 2 nd law}

N=4 × 4=16 {N}
