Block A of weight 100 N rests on a frictionless inclined plane of slope angle 30° as shown in the figure. A flexible cord attached to A passes over a frictionless pulley and is connected to block B of weight W. Find the weight W for which the system is in equilibrium.
  • a)
    25 N
  • b)
    50 N
  • c)
    75 N
  • d)
    100 N
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Block A of weight 100 N rests on a frictionless inclined plane of slop...
As the system is in equilibrium,
∴ T = W …(i)
and T = mg sin30 …(ii)
From (i) and (ii), we get

W = mg sin 30 = (100 N) × 1/2 = 50 N
