Mixed Laws of MotionHardQuestion 5448

Question

Three blocks (2 kg, 3 kg, 5 kg) are connected in series on frictionless surface. Force F = 30 N on the 5 kg block. Tension between 3 kg and 2 kg blocks is:
  1. A
    3 N
  2. B
    6 N
    Correct
  3. C
    9 N
  4. D
    15 N

Correct answer

6 N

Explanation

a = F/(2+3+5) = 30/10 = 3 m/s². Tension on 2 kg block: T = 2×3 = 6 N.
