JEE MainPhysicsLaws of MotionMCQ+4 / −1
A block 'A' takes 2 s to slide down a frictionless incline of 30 ∘^\circ∘ and length 'l', kept inside a lift going up with uniform velocity 'v'. If the incline is changed to 45 ∘^\circ∘, the time taken by the block, to slide down the incline, will be approximately :
  1. A
    2.66 s
  2. B
    0.83 s
  3. C
    1.68 s
  4. D
    0.70 s
