SSC Selection Post 2023 PYQ — Question 50

The correct answer is option 4 i.e. Centripetal.

 

The centre-seeking force is scientifically known as the centripetal force. It is the force that acts on an object moving in a circular path, directing it toward the center of the circle or axis of rotation.

For example:

• When a stone is tied to a string and whirled in a circle, the tension in the string provides the centripetal force that keeps the stone moving in its path.

• In planetary motion, gravitational force acts as the centripetal force that keeps planets in orbit around the sun.

Other Options:

• Van der Waals: Weak intermolecular forces, not related to circular motion.

• Centrifugal: A fictitious or apparent force that seems to push objects away from the center in a rotating frame.

• Gravitational: A force of attraction between masses; can act as a centripetal force in certain contexts but is not its synonym.
