JEE AdvancedPhysicsLaws of MotionMCQ+3 / −1
A block of base 10 cm × 10 cm and height 15 cm is kept on an inclined plane. The coefficient of friction between them is 3\sqrt 33​. The inclination θ of this inclined plane from the horizontal plane is gradually increased from 0∘0^\circ0∘. Then
  1. A
    at θ = 60∘60^\circ60∘, the block will start sliding down the plane
  2. B
    the block will remain at rest on the plane up to certain θ and then it will topple
  3. C
    at θ = 60∘60^\circ60∘, the block will start sliding down the plane and continue to do so at higher angles
  4. D
    at θ = 60∘60^\circ60∘, the block will start sliding down the plane and on further increasing θ, it will topple at certain θ
