A65 kg horizontal force is just sufficient to draw 1300 kg block at level table surface at uniform speed. Then, the coefficient of friction is:

A

0.5

B

5

C

0.02

D

0.05

Text Solution

Verified by Experts

The correct Answer is:
d
Here acceleration is zero .: `F_(f) =` applied force =` 65 xx 9.8 N`
Now `F_(f)=mu=(F)/(R)=(65xx9.8)/(1300xx9.8)=0.05`
Hence correct choice is (d)
