If a new planet is discovered rotating around Sun with the orbital radius double that of earth, then what will be its time period (in earth's days)

A

1032

B

1023

C

1024

D

1043

Text Solution

Verified by Experts

The correct Answer is:
A
By Kepler's third law, `T^(2) prop R^(3)`
`:. ((T_(2))/(365 daya)) = ((2r)/(r))^(3)`
`T_(2) = 365 xx 2sqrt(2) = 1032` days
