To solve this problem we will apply the concept given by the law of gravitational attraction, which properly defines gravity under the function

Here,
G = Gravitational Universal Constant
M = Mass of Earth
r = Distance between the human and the center of mass of the Earth
The acceleration due to gravity when is 4 times the mass of Earth and 3 times the radius would be given as,




The weight is defined as

So the new weight would be given as






Therefore the weight under this condition is 288.8N
Answer:
Explanation:
As per the spectrum range, it is important to observe the Sun and other astronomical objects from Earth's surface because they lie in the visible band of spectrum.
Earth's atmosphere absorbs ultraviolet light coming from the space thus helps us to know and learn about their properties.
If we place telescope in space, would be covered with water droplets thus making it useless to study about any object or to see them hence proper place such as Earth's atmosphere is well suited to observe stars and other celestial bodies.
