Question
The radius of orbit of a planet is two times that of earth. The time period of planet is $\ldots \ldots \ldots$ years.(A) $4.2$(B) $2.8$(C) $5.6$(D) $8.4$
Step 1
Mathematically, this can be written as: (T1/T2)^2 = (R1/R2)^3 where T1 and T2 are the time periods of the two planets, and R1 and R2 are their respective radii of orbit. Show more…
