Question

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:

Answer:

B

Solution:

Acceleration of box = $10 m s^{- 2}$
Inside the box forces acting on bob are shown in the figure.

$T = \sqrt{{(mg)}^{2} + {(ma)}^{2}} = 10 \sqrt{2} N$
