Answer:
The value of g in Kepler-12b is 
Explanation:
To determine the value of g at Kepler-12b it is necessary to combine the equation of the weight and the equation for the Universal law of gravity:
(1)
Where m is the mass and g is the value of the gravity
(2)
Equation (1) and equation (2) will be equal, since the weight is a force acting on the object as a consequence of gravity:
(3)
Then g will be isolated from equation 3:
(4)
The radius of Jupiter has a value of 69911000 meters, so its diameter can be determined by:
(5)
Where d and R are the diameter and radius of Jupiter


Procedure for finding the radius of Kepler-12b:
For the case of Kepler-12b it has a diameter that is 1.7 times that of Jupiter



By means of equation 5 the radius of Kepler-12b can be known:



Procedure for finding the mass of Kepler-12b:
The mass of Jupiter has a value of
kilograms
For the case of Kepler-12b it has a mass that is 0.43 times that of jupiter



The value of g in Kepler-12b can be found by replacing its radius and mass in equation 4:


Hence, in Kepler-12b the gravity has a value of
