Find minimum normal force to be each hand to hold there identical books in verticle position Each books has mass `m` and the value of coefficient of friction between the books as well as between hand and the book is `mu`

A boy presses a book against the front wall such that the book do not move the force of friction between the wall and the book is

A man holds a 2 kg book between his palms so that each hand exerts the same horizontal force on the book.The coefficient of static friction between the palms and the book is 0.4 and g= 10m s^(-2) .If the book is prevented from falling,the least force exerted by each hand on the book is ?

A man holds a 2 kg book between his palms. so that each hand exerts the same horizontal force on the book. The coefficient of static friction between the palms and the book is 0.4 and g = 10ms^(-2) . If the book is prevented from falling, the least force exerted by each hand on the book is

A man holds a book vertically between his two palms so that it does not fall. The mass of book is 1 kg and the force exerted by each palm is 2.5 kg xxg . Find the coefficient of friction between the book and the palm.

Work is done when we hold a pile of books in our hands.

A student holds a book of mass 2kg between his hands.Each hand exerts horizontally a force of 50N .Then the coefficient of static friction is
