Two planets at mean distance d_1 and d_2 f

Your Ultimate Guide to JEE & NEET Question Solutions

Two planets at mean distance ${d_1}$ and ${d_2}$ from the sun and their frequencies are $n_1$ and $ n_2$ respectively then

A

$n_1^2d_1^2 = {n_2}d_2^2$

B

$n_2^2d_2^3 = n_1^2d_1^3$

C

${n_1}d_1^2 = {n_2}d_2^2$

D

$n_1^2{d_1} = n_2^2{d_2}$

Two planets at mean distance ${d_1}$ and ${d_2}$ from the sun and their frequencies are $n_1$ and $ n_2$ respectively then

$\frac{{{T^2}}}{{{R^3}}} = \frac{{{T^2}}}{{{d^3}}} = \frac{1}{{{n^2}{d^3}}} = $ constant

$\therefore \,\,\,n_1^2d_1^3 = n_2^2d_2^3$        [where $n =$ frequency]
