Originally posted by: akhlNext question from me: -
A book is kept on a table-top, which is horizontal. Coefficient of static friction between the book and the table = 0.2Weight of the book is 10 N. Thus normal force from the table = 10 N.The book is pushed with a horizontal force of 1 N. What is the magnitude of the force of friction by the table on the book? No need of FBD. Just show the calculations and the final answer.
Lets calculate
Maximum value of static friction =uN
Where u= coefficient of static friction
N= Normal reaction
Here u= 0.2 and N=10
So maximum value of static friction=0.2*10= 2N
This value is more than 1N, applied force
So the friction force will adjust itself to 1N and the Book will not move and remain stationary
So value of friction force= 1N and direction opposite to applied force
