Question

A book of mass 1kg is on a table If a force of 3N is applied tangentially along the plane
of a table, the book tends to move. Calculate the coefficient of static friction between the
table and book.

Answer 1

Explanation:

you should prefer Vedantu more better than this

Answer 2

Answer:0.3

Explanation:

Since the book tends to move

=> Static friction ( limiting) is defined.

Now we know fr=¶N

(take coefficient of limiting fr=¶)

Also for limiting friction force= friction( by Newton's law)

=>3=¶N

(N=Mg=10)

=>¶=3/10=0.3

Hope this helped you...
