Answer :
Formula of Coefficient of friction= F/N
Force applied on the block =47N (Provided in the question)
Mass of the body=15kg (Provided in the question)
Normal force applicable on the body(N)=m x g
N= m x g
Where N represents the Normal Force, m the mass of the body and g represents the gravitational force.
N= 15 x 9.8
N=147N
When a force is applied on a body that is less than that of the Limiting force ( the maximum static friction that can be there) then the friction force produced as a reaction to that force is equal and opposite in nature, acting on the same body.
Since a 47N force is applied on the block a static friction force of the same value will pull the body in the opposite direction.
Thus force due to Friction=47 N
Coefficient of Friction= Friction/ Normal Force
Coefficient of friction =47/147
coefficient of friction=0.319
coefficient of friction≈0.32
