MHT CET 2024 Physics question
The acceleration due to gravity at the surface of the planet is same as that at the surface of the earth, but the density of planet is thrice that of the earth. If 'R' is the radius of the earth, the radius of the planet will be
Answer: (B)
Solution
For a uniform planet of radius and density , the surface gravity is , so . With equal , . Since
