केपलर के नियमानुसार उपग्रह का आवर्तकाल इसकी त्रिज्या के साथ निम्न प्रकार से परिवर्तित होगा

A

${T^2} \propto {R^3}$

B

${T^3} \propto {R^2}$

C

${T^2} \propto (\frac{1}{R^3})$

D

${T^3} \propto (\frac{1}{R^2})$

Solution

According to Kepler's third law of planetary motion, "The square of a planet's orbital period is proportional to the cube of the length of the semimajor axis of its orbit."

So, $T ^2 \propto R ^3$
