Answer:
Electric charge in the earth will be
Explanation:
We have given that E = 116 N/C
Radius of the earth R = 6371 km = 6371000 m
We have to find the electric charge in the earth '
We know that electric field due to charge is given by . here K is coulomb's constant
So
So electric charge in the earth will be
The tiny space invader and the new space station will have equal orbital speed.
<h3>The orbital speed of satellite </h3>
The orbital speed of satellite on Earth surface is given as;
where;
- V is the orbital speed
- G is universal gravitation
- M is mass of the Earth
- r is the radius of the circular path
Since the two objects are at the same height from Earth's surface, the distance from the central point (r) will be the same. Thus, the two objects will have equal orbital speed.
