Coefficient of friction byjus

WebCofficient of Friction is the value which shows relation between frictional force andnormal force. μ is completely experimental F = μN A coefficient of friction that is more than one just means that friction is stronger than the normal force. Hence it may be less than 1 equal to 1 or greater than 1.. Therefore Option (D) Physics Standard XII WebCoefficient of friction between 5 kg and 10 kg block is 0.5. If friction between them is 20 N, the value of force being applied on 5 kg (in N) is (Assume that the floor is frictionless) Solution The limiting friction between 5 kg and 10 kg is fl2 =50×0.5 =25N. Since 20< 25, the two blocks are moving with a common acceleration.
