A cylinder of mass 10 kg is rolling perfectly on a plane of inclinatio

1.	A cylinder of mass 10 kg is rolling perfectly on a plane of inclination 30°. find the force of friction between the cylinder are the surface of inclined plane. (μ = \(\frac{1}{3}\))
Answer» Using, f = μmgcos θ, We get \(f=\frac{1}{3}\times 10 \times 9.8 \times cos\, 30°\) \(=\frac{1}{3}\times 10 \times 9.8 \times \frac{√3}{2}\) = 28.25 N

Answer»

Using, f = μmgcos θ,

We get \(f=\frac{1}{3}\times 10 \times 9.8 \times cos\, 30°\)

\(=\frac{1}{3}\times 10 \times 9.8 \times \frac{√3}{2}\)

= 28.25 N
