WHAT IS THE COEFFICIENT OF STATIC FRICTION BETWEEN A LOAD OF MASS 2KG AND A HORIZONTAL SURFACE, IF THE LIMITING FRICTIONAL FORCE IS 10N

The answer to the question is: B. 0.5

The coefficient of static friction can be calculated using the formula:

coefficient of static friction (μs) = limiting frictional force (Ff) / normal force (N)

In this case, the limiting frictional force (Ff) is given as 10N and the mass (m) is 2kg.

The normal force (N) can be calculated using the formula N = mg, where g is the acceleration due to gravity (10 ms^-2).

N = mg = 2kg * 10 ms^-2 N = 20N

Now, we can calculate the coefficient of static friction:

μs = ?

Ff = 10N

N = 20N

μs = Ff / N

μs = 10N / 20N

μs = 0.5

Therefore, the coefficient of static friction between the load of mass 2kg and the horizontal surface is 0.5.
