If you stood on a planet with four times the mass of Earth, and twice Earth's radius, how much would you weigh?

1/4 times your earth's weight

Explanation:

assuming the Mass of earth = M

Radius of earth = R

∴ the mass of the planet= 4M

the radius of the planet = 4R

gravitational force of earth is given as =

where G is the gravitational constant

Gravitational force of the planet =

                                                       =

                                                       =

recall, gravitational force of earth is given as =

∴Gravitational force of planet = 1/4 times the gravitational force of the earth

you would weigh 1/4 times your earth's weight

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
