Question

A cubical box of 10 kg and a cuboidal box of 10 kg is kept on a surface, will the static friction on them will be same or different? Give reasons for your answer.

Answer 1

Answer:

First calculate the static friction force.

At bottom surface friction coefficient is 0.5

F

=(2+8)g=10×10=100N

Thus,

F

=μN

=0.5×100N

=50N
