Question

A stretching force of 5 N is applied at one end of a spring balance and an equal stretching force is applied at the other end at the same time. The reading on the balance will be ______.

विकल्प

• 5 N

• 10 N

• 2.5 N

• zero

Answer 1

A stretching force of 5 N is applied at one end of a spring balance and an equal stretching force is applied at the other end at the same time. The reading on the balance will be 5 N.

Explanation:

A spring balance measures the tension in the spring, not the sum of the forces. When equal and opposite forces of 5 N act at both ends, the tension in the spring is 5 N.
