Question 1 3 pts Planet A and Planet B orbit a star in circular orbits. The orbital radius (distance from the star) of Planet

Answer 1

Answer #1

escape velocity, v = sq. root(GM/R)

where G= gravitation universal constant

M= mass of planet

R = radius of planet

now ratio of M is given but no information is given about radius of planets

orbital radius is given but that is not required here.

so not enough information to know

Answer 2
