Question

the magnitude of the acceleration of a planet in orbit around the sun is proportional to

Answer 1

the magnitude of the acceleration of a planet in orbit around the sun is proportional to mass of sun

Answer 2

"The answer is, “The magnitude of the acceleration of a planet in orbit around the sun is proportional to the mass of the sun.”

This is mainly with the help of the formula gravitational force which is,

F = G * M * m/ r^2

If the F = m * g

Then.

mg = G * M * m/r^2

hence,

g = G * M/ r^2
