Question

A particle of mass 1kg, initially at rest, starts sliding down from the top of a frictionless inclined plane of angle \frac{𝜋}{6}$$\frac{\pi}{6} (as schematically shown in the figure). The magnitude of the torque on the particle about the point O after a time 2seconds is ______N-m. (Rounded off to nearest integer)

(Take g = 10m/s2)

Answer 1

The correct answer is: 85 to 88 (approx)
