Which of the following graphs represents the motion of the planet moving around the Sun.T is the
period of revolution and r is the average distance (from centre to centre) between the Sun and the
planet
A
B
C
D
T2αr3[Kepler′s third law]
A planet moves around sun in nearly circular orbit period of revolution 't', radius of orbit r mass of sun m.
Time period if direcyly proportional to mass of sun, distance between planet and sun and universal gravitational constant.
Prove T2 is directly proportional to r3
The distance of a planet from the sun is 5 times the distance between the earth and the sun. The time period of revolution of the planet is
