Question 50

A particle of mass 10 kg rests in equilibrium on a smooth plane inclined at 30° 30°\,30° to the horizontal. A horizontal force of magnitude P P\,P N acts on the particle in the vertical plane containing a line of greatest slope, pushing it into the plane.

Use g=9.8g=9.8g=9.8 m s−2^{-2}−2.

a.
