. A body of mass 100 g is made just to slide on a rough surface by applying a force of 0.4 N. Then the coefficient of friction is ______ ×10 to the power -1 .(g =10ms to the power -2)
Answers
Answer: Friction
Explanation:
Friction is a force that is around us all the time that opposes relative motion between systems in contact but also allows us to move (which you have discovered if you have ever tried to walk on ice). While a common force, the behavior of friction is actually very complicated and is still not completely understood. We have to rely heavily on observations for whatever understandings we can gain. However, we can still deal with its more elementary general characteristics and understand the circumstances in which it behaves.

Answer:
If μ be the coefficient of friction, the friction force f=μmg
As the friction force opposes the motion, so in equilibrium, the friction force is equal to the applying force.
So, μmg=0.8 or μ=
(0.1)(10)
0.8
=0.8=8×10
−1
Thus, the value of x is 1.
