Question

Explain kepler's third law.

Answer 1

According to keplers third law the square of time peruod of satelite around the sun is directly proportional to cube of its diatance from the sun of semi major axis.

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, 

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

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