All surfaces shown in figure are assumed to be frictionless and the pulleys and the string are light. The acceleration of the block of mass 2 kg is:

  1. g
  2. g3
  3. g2
  4. g4

Solution

For 4 kg block:

40-2T=4a⇒T=20-2a

For 2 kg block:

T-10=4a⇒20-2a-10=4a⇒10=6a⇒a=106=g6 m s-2

Acceleration of the block of mass 2 kg, 2a=g3 m s-2.
