Question

A body of mass \(10\,\text{kg}\) is moving up on an inclined plane of \(30^\circ\) with an acceleration \(2\,\text{m s}^{-2}\). Find the force required, if the coefficient of friction between the object and the plane surface is \(\frac{\sqrt{3}}{6}\), [given \(g = 10\,\text{m s}^{-2}\)].

• A. \(1.95\,\text{N}\)
• B. \(9.5\,\text{N}\)
• C. \(19\,\text{N}\)
• D. \(95\,\text{N}\)

Hint:

When a body moves up an inclined plane, both friction and the component \(mg\sin\theta\) act downward along the plane.

Answer 1

The Correct Option is D
