Question

A block is sliding on a rough horizontal surface .if the contact force on the block is root3 times of the frictional force is(Nis normal force)

Answer 1

Answer:

very eassy

Explanation:

Let coefficient of friction be x

contact force =√(f^2+N^2)

√(f^2+N^2)=√2f

S.O.B.S

f^2+N^2=2f^2     

N^2=2f^2-f^2

N^2=f^2

N^2=x^2.N^2          (f=x.N)

x^2=1

x=1

coefficient of friction=1
