Question

Find the acceleration due to gravity on a planet that is 10 times as massive as the earth and with
radius 20 times of the radius of the earth( g=9.8m/s2)​

Answer 1

Answer:

hope it helped uh.........

Answer 2

The acceleration due to gravity is $0.245m/s^{2}$

Step by step calculation:

Given data:

Mass of the planet$=10M_{E}$

Radius of the planet$=20r_{E}$

$g=9.8m/s^{2}$

To find:

We need to find the acceleration due to gravity.

Formula to be used:

$g=\frac{GM}{r^{2} }$

g$=$acceleration due to gravity

G$=$Gravitational constant

M$=$mass

r$=$radius

Solution:

$g=\frac{GM_{E} }{r_{E} ^{2} }$ and $g_{p}=\frac{GM_{p} }{r^{2} _{p} }$

Let $g_{p} =$acceleration due to gravity

$g_{p}$$=(G$×$10M_{E}$)/$(20r_{E} )^{2}$

$g_{p}=(10GM_{E})/(400r^{2} )$

$g_{p} =\frac{1}{40} g$

$0.245m/s^{2}$

Therefore, the acceleration due to gravity is $0.245m/s^{2}$.
