Question

31 : What is the co-efficient of friction if a force
of 30 N is required to move a body of mass 35 kg​

Answer 1

Answer:

mu= 30/350= 0.08

............

Answer 2

Answer:

F = co-efficient of friction×N

Step-by-step explanation:

N= mg

N= 10×35

N= 350 KN = 350000N

therefore co-efficient of friction= F/N

co-efficient of friction= 30/350000

co-efficient of friction= 3/35000
