Question
Find the odd man out:
Options
Force responsible for a string to become taut on stretching
Weight of an object
The force due to which we can hold an object in hand.
Solution
Force responsible for a string to become taut on stretching, Weight of an object, The force due to which we can hold an object in hand - 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
