Find the odd man out : (i) Force responsible for a string to become taut on stretching(ii) Weight of an object (iii) The force due to which we can hold an object in hand.

Answer»

Weight of an object. 

Reason: Weight of an object (force due to gravity) is a non-contact force while force responsible for a string to become taut (tension force) and force due to which we can hold an object in hand (normal force) are contact forces.
