Question

A planet moves around the sun in a circular orbit. The time period of revolution 't' depends upon the radius 'r' of the orbit, mass of the sun 'm' and gravitational constant 'g'. Establish a physical relation using dimensional analysis

Answer 1

Answer:

check the photo.

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.
