Question

State and explain Kepler's third law of planetary motion with diagram

Answer 1

Hey There! The squares of the sidereal periods of revolution of the planets are directly proportional to the cubes of their mean distances from the Sun. 





HOPE THIS HELPED YOU.......

Answer 2

$\huge\textbf{Kepler's Third Law :}$

According to it the square of time period of revolution of planet around sun is directly proportional to the cube length of semi major axis.

i.e. ${T}^{2}$ $\alpha$ ${R}^{3}$

Here T is time period of revolution and R is the distance of planet from the earth.

When we remove the sign of directly proportional then we have have to write some constant.

So, 

${T}^{2}$ = $k$ ${R}^{3}$

$\frac{{T}^{2}}{{R}^{3}}$ = $k$
