Two rectangular blocks of masses 40 kg and 60 kg are connected by a string and kept on a frictionless horizontal table. If a force of 1000 N is applied on 60 kg block away from 40 kg block, then the tension in string is

Options

  1. A450   N
  2. B400   N
  3. C350   N
  4. D500   N

Correct answer

B. 400   N

Step-by-step solution

Acceleration of the combined system, a = 1000 100 = 10   m   s - 2 . Now for the left block we can write, T = m a = 40 × 10 = 400   N
