A newly discovered planet has twice the mass and three times the radius of the earth. What is the free-fall acceleration at its surface, in terms of the free-fall acceleration g at the surface of the earth?
a. 1/9 g
b. 2/3 g
c. 3/4 g
d. 4/3 g
E. None of these
Alright
Dude, If that worked for you... dont forget to give THUMBS UP.(that
will work for me!)

If I missed something feel free to leave a comment.
atleast before giving downvote.
and, Thanks for using Chegg- Smarter way to study.
A newly discovered planet has twice the mass and three times the radius of the earth....
A planet has twice the mass of Earth and twice the radius of Earth. The free-fall acceleration on this planet is equal to what?
A hypothetical planet has a mass 3 times that of the Earth and a radius twice that of the Earth. Calculate the value for acceleration due to gravity near the surface of this hypothetical planet.
9. A newly discovered planet has a density p 3Pearth and a radius R 2Rearth The gravitational acceleration g' on the surface is this planet is (a) 6g (b) 3g (d) 3g/2 (e) 39/4 where g is the gravitational acceleration on the surface of the earth
A hypothetical planet has 3 times the mass of Earth and twice the radius of the Earth. What is the surface gravity on this planet? r = Rplanet g = GMplanet / r2
The radius of a planet is three times that of Earth and its mass is nine times that of Esrth. The acceleration due to gravity on this planet is
Planet X has 20 times the mass of the earth and 3 times the earth's radius. It orbits star Y at a distance of 8 AU, where 1 AU is the earth-sun distance. Star Y has twice the mass of our sun. (a) What is the orbital period of Planet X in years? (b) An astronaut has an earth weight of 120 lbs. What is her weight on the surface of planet X?
Planet X has free-fall acceleration 8 m/s2 at the surface. Planet Y has twice the mass and twice the radius of planet X. On Planet Y g = 2 m/s2 g = 4 m/s2 g = 8 m/s2 g = 16 m/s2 g = 32 m/s2
A spherically symmetric planet has 2 times the Earth's mass and twice its radius. If a jar of peanut butter weighs 12N on the Earth, how much would it weigh on the surface of this planet? depends if it's Skippy creamy or super-chunky peanut butter.
A hypothetical planet has a radius 1.2 times that of Earth, but has the same mass. 1.)What is the acceleration due to gravity near its surface? Express your answer to two significant figures and include the appropriate units.
Part A.) A creature with mass of 3.1 kg on earth, is pictured on planet W which is twice as massive as Earth and has twice Earth's radius. What is the creature’s weight on planet W? -answer choices a.) 11 N b.) 9.8 N c.) 4.3 N d.) 15 N Part B.) What is the local value of g on Planet W? -answer choices a.) 3g/4 b.) g/2 c.) g d.) 2g Part C.) An asteroid is on collision course...
