The potential energy of the satellite is 441*10^8 J
The distance from the earth's surface is -0.4775*10^7 m.
Explanation:
The potential energy is the energy which is stored in the object due to its relative position or due to the electric charge.
Potential energy can be calculated by using formula:
PE = m*g*h
where m = mass of the object in kg's = 5000 kg,
g = gravitational field strength = 9.8 m/s²,
h = height of the object in meters = 900*10³ m.
substituting the given values of mass of satellite and height from the earth's surface.
PE = 5000*9.8*900*10³
PE = 441 * 10^8 J
Now in the next question we are asked to find distance
Given data :
mass of satellite (m) = 10,000kg ,
PE = -4.68*10^11 J .
PE = m*g*h
-4.68*10^11 = 10,000*9.8*h
h = (-4.68*10^11)/(10*10³*9.8)
h = -0.4775 * 10^7 m
Therefore, in the first question potential energy = 441*10^8 J , and second question height = -0.4775*10^7 m
