A man hold a book weighing 1kgwt between his hand and keeps it from falling by pressing both hand against the book with a force of 2.5kgwt each.Find coefficient of friction between book and hand.plz solve it by attaching a pic of FBD of this question.

Question

Atul Nagar · Answer

The weight of book is acting downward while a horizontal force of 2.5 kgwt is holding the book. Book is also applying normal reaction N of 2.5 kgwt on hand. therefore mg = frictional force, f mg = n N ; n = coeffeicient of friction n = 1/(2.5) = 0.4
