Question

A 2 kg box sits on a 3 kg box which sits on a 5 kg
box. The 5 kg box rests on a table top. What is the
normal force exerted by the 5 kg box on the 3 kg
box?​

Answer 1

Answer:

The Normal force exerted by the 5 kg box on the 3 kg box is 50N.

Explanation:

Given data:

Box1= 2kg

Box2= 3kg

Box3= 5kg

Mass of the boxes1 & 2, M= 2+3+=5

acceleration, g =10m/s^2

By balancing the forces at the point of contact;

N= Mg

N= (5×10)

Hence, the normal force applied by box3 upon box2 is 50N.

Therefore, SOLVED!
