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$.........\,N$ (Take $g =10\,m / s ^2$ )

In order to test the strength of a rope, one end is tied to a large tree and the other end is hitched to a team of $2$ horses. The horse pull as hard as they can, but cannot break the rope. If the rope is untied from the tree and attached to another team of $2$ horses with equal strength, and the two teams pull in opposite directions, the tension in the rope will
