The gravitational attraction between the satellite and the Earth provides the centripetal force that keeps the satellite in circular motion, so we can write
where
G is the gravitational constant
is the Earth's mass
m is the satellite's mass
is the Earth's radius
is the altitude of the satellite above the Earth's surface
v is the orbital speed
Solving the formula for v, we find
2) 1.73 hours
The period of the orbit is the time taken to complete one revolution around the Earth, therefore:
where the numerator is the circumference of the orbit and v the orbital speed, therefore we find
Converting into hours,
Answer:
<h2>Magnetic field strength in that region is 1.2 T</h2>Explanation:
As we know by the formula of radius of charge moving in external field is given as
so we will have
now we have
now we have
