Question

a planet moves around the sun (M) ina circular orbit.Itbis given it's time period of evolution (T) depends on radius (r) of the orbit. if the universal gravitation constant is G. Find the expression of T ?​

Answer 1

Answer:

Explanation: A planet moves around the sun in nearly circular orbit. Its period revolution 'T' depends upon radius of orbit, mass of the sun and the gravitational constant. Hence, The square of time period is directly proportional to the cube of the radius of the orbit.
