Question
Question: Two planets at mean distance \(d _ { 1 }\) and \(d _ { 2 }\) from the sun and their frequencies are ...
Two planets at mean distance d1 and d2 from the sun and their frequencies are n1 and n2 respectively then
A
n12d12=n2d22
B
n22d23=n12d13
C
n1d12=n2d22
D
n12d1=n22d2
Answer
n22d23=n12d13
Explanation
Solution
R3T2=d3T2=n2d31=constant
∴n12d13=n22d23 [where n = frequency]
