- Both the mass and the radius of the planet are half as that of the Earth
- Radius of the planet is half as that of the Earth, but the mass is the same as that of the Earth
- Both the mass and the radius of the planet are twice as that of the Earth
- Mass of the planet is half as that of the Earth, but radius is same as that of the Earth
Answer
(B) Radius of the planet is half as that of the Earth, but the mass is the same as that of the Earth
