Question

if certain planet year is 11 times that of earth, calculate the distance of the planet from the sun​

Answer 1

Applying the Kepler's law of time,

T2/R3=T''2/R''3

==> T2/R3=(11T)2/R''3

R''3=T2/R3*(11T)2

Where T is the actual time taken by the earth

and T'' is the time taken by the planet which is 11 times the earth's time

R is the distance b/w the earth and the sun

R'' is the distance b/w the sun and the planet.

NOTE:- Don't take time in days but in years.
