Question

A force of 98 newton is required to pull a body of mass 1 x 10²kg over the surface
of the ice then the co-efficient of friction is (g = 9.8ms-2)
102
2) 0.3
3) 0.1
4) 0.5
ADOL hlock is in motion on a rough horizontal surface. A horizontal force of 60N​

Answer 1

Answer:

the correct answer is 3.

Step-by-step explanation:

m=100 kg , g=9.8 m/s

F=98 N

F"=mg

F"=100×9.8

f"=980 N

F=μF"(force normal)

98=μ·980

98/980=μ

0.1=μ
