Question

What is the normal reaction between A and B blocks if the system is in equilibrium? {g=10m/s2}

​

Answer 1

Answer:

For equilibrium of 2kg−

T=2g where g=9.8m/s

2

And for equilibrium of 5kg−

⟹T+N=5g

⟹N=5g−T=3g

⟹N=3×9.8

⟹N=29.4N$\huge\red{➳Ṧřîⅉꫝᾇñ ࿐}$

Explanation:

Answer 2

Given,

Mass of block A=1kg,

Mass of block B=2kg,

System is in equilibrium.

To Find,

The normal reaction between A and B blocks.

Solution,

For equilibrium of block B(2kg),

We know, T=2g where g=9.8m/s

Also for equilibrium of block A(1kg)

As we know, T+N=3g

⟹N=3g-2g

⟹N=g

⟹N=10N

Hence, the normal reaction between A and B blocks is 10 N.
