Question

The gravitational acceleration on a planet with twice the force and diameter of the earth is ......... m / sec2.

Answer 1

Answer:

78.4m/s^2

Explanation:

mass on that planet is 32 times of earth

radius of that planet is 4 times of earth

Answer 2

The gravitational acceleration on a planet with twice the force and diameter of the earth is 19.6 m/s².

Explanation:

Given: Force = Mass, M = 2M.

Diameter, D = 2x $\frac{R}{2}$ ⇒ R. Since the acceleration on a planet is twice in force and diameter. So,

Let 'g' be the acceleration due to gravity of the earth having diameter ‘D’ and Mass ‘M’. We know that  $g = \frac{GM}{R^{2}}$

Now for the planet having Mass = 2M and Diameter, D = R, then

$g = \frac{GM}{R^{2}}$= G x $\frac{2M}{R^{2}}$ = 2 x $\frac{GM}{R^{2}}$ = 2.g

g = 2 x 9.8 = 19.6 m/s²

The gravitational acceleration on a planet is 19.6 m/s².
