Consider a small block sliding down an inclined plane of inclination with the horizontal. The coefficient of friction is where is the distance (in meter) through which the mass slides down. The distance covered by the mass before it stops is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
By equilibrium of block perpendicular to the incline, N=mgcosθ. So kinetic friction is, fk=μN=μmgcosθ. Work done by constant force is given as, W=FScosθ. Let distance covered by the mass is x before coming at rest. So,…
