Inside a horizontally moving box, an experimenter finds that when an object is placed on a smooth horizontal table and is released, it moves with an acceleration of 10 m s - 2 . In this box, if 1 kg body is suspended with a light string, the tension in the string in equilibrium position (with respect to experimenter) will be (Take g = 10 m s - 2 )

Options

  1. A10   N
  2. B1 0 2 N
  3. C20 N
  4. DZero

Correct answer

B. 1 0 2 N

Step-by-step solution

Acceleration of box = 10   m   s - 2 Inside the box forces acting on bob are shown in the figure. T = mg 2 + ma 2 = 1 0 2 N
