Answer:
Distance, r = 3721.04 meters
Explanation:
It is given that,
Charges on both humans,
Electric force of attraction between them, F = 650 N
We need to find the separation between two humans. It can be solved using the following formula as :
r = 3721.04 meters
So, the distance between the humans is 3721.04 meters. Hence, this is the required solution.
Velocity is computed using the formula:
Where:
V = speed
d = distance traveled
t = time/period
First you need to consider that the orbit is circular. To get the measurement or the distance going around Earth, you will need to get the circumference of the path.
Where:
C = circumference
π = 3.14
r = radius
The Earth has a radius of 6,400km, but you also need to consider that the satellite is orbiting above the surface of the Earth, so you add in the 2,000km to that radius.
r = 6,400Km + 2,000Km = 8,400Km
Next step is to insert that into our circumference formula:
The distance traveled would then be 52,778.76Km
Now that we have the distance, we can then get the velocity:
The speed of the satellite is 4,398.23km/hr.
