Question

By applying Kepler's third law to the formula for centripetal force, Newton concluded that the force acting on a planet is:

विकल्प

• Inversely proportional to its mass

• Directly proportional to square of its distance from sun

• Inversely proportional to square of its distance from sun

• Directly proportional to its period of revolution

Answer 1

Inversely proportional to square of its distance from sun

Explanation:

The derivation leads to F ∝ \[\frac {1}{r^2}\]​, which is the inverse square law for gravitation.
