Show that a cylinder will slip on an inclined plane if the coefficient of static friction between the plane and the cylinder is less than `1/3tantheta` where `theta` is the angle of the inclination with the horizontal.

Options

A. `1/3 tan theta `
B. `1/3 sin theta `
C. `2/3 tan theta `
D. `2/3 sin theta `

Answer

A

Explanation

`mu = tan theta ((k^(2)//R^(2))/(k^(2)/(R^(2)) + 1 ))`
