Question

A body of mass 100g is sliding on an inclined
plane with an inclination of 60°. What is the
frictional force experienced, if coefficient of friction
is 1.7 ? (take g = 10 m/s2) ​

Answer 1

Answer:

the question is solved in the picture

Answer 2

Answer:

8500 N

Explanation:

We know that

Body of mass m = 100 g

Plane of the inclination is Ф = 60 degree

Coefficient of friction is  μ = 1.7

        g = 10 m/s²

Now  ,

We know that,

Normal force  f = mg cosФ

So

             f =  100 × 10 × cos 60

             f = 5000 N

Now  

Frictional  Force = Coefficient  of friction × normal force

F = μ f

F = 1.7 × 5000

Frictional force is F = 850 N

Correct answer is  850 N
