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.

            (w.r.t. experimenter) will be. (Take g = 10 m/s^2)

Since the object slides with acceleration 10m/s^2,  the acceleration of box is10m/s^2. Inside the  box a body suspended experiences a pseudo force.

T=m\sqrt{a^2+g^2}

T=10\sqrt2
