Question

A block A is kept on a rough plate with coefficient of static friction $μ_{s} = 1.33$ and coefficient of kinetic friction $μ_{k} = 1.0$ . The plate is leaning with the horizontal at an angle $θ = tan^{- 1} (μ_{s}) = 53^{\circ}$ , as shown in the figure. If the plate is further tilted slightly, the acceleration of the block just after the tilt is: (Take $g = 10$ m/s², $sin 53^{\circ} = 0.8$ , $cos 53^{\circ} = 0.6$ )

Options:

Answer:

A

Solution:

$a = g (sin 53^{\circ} - 1.0 \times cos 53^{\circ}) = 10 (0.8 - 0.6) = 2 m/ s^{2} .$

Option A.
