The velocity of Satellite A is 2% greater than velocity of satellite B.
The given parameters;
- <em>Altitude of Satellite A = 500 km</em>
- <em>Altitude of Satellite B = 800 km</em>
The forces acting on the Satellites are given as follows;


Thus, the velocity of Satellite A is 2% greater than velocity of satellite B.

Since the acceleration is uniform, we can calculate it from the data we are given:
a = (vf - vi)/2
where vf=33 m/s and vi=11 m/s
Then use Suvat's equation:
x(t) = vi*t + 0.5 * a * t
where t=20s

Explanation:
The complete question is
You have a coil of wire with 17 turns each of 1.5 cm radius. You place the plane of the coil perpendicular to a 0.50-TB? field produced by the poles of an electromagnet.
Find the magnitude of the average induced emf in the coil when the magnet is turned off and the field decreases to 0 T in 1.9 s .
Radius of the coil = 1.5 cm = 0.015 m
number of turns = 17
Initial magnetic field
= 0.50 T
Final magnetic field
= 0 T
time taken dt = 1.9 s
Area pf the coil = π
= 3.142 x
= 7.1 x 10^-4 m^2
magnetic flux = BA
initial flux =
A = 0.5 x 7.1 x 10^-4 = 3.55 x 10^-4 Wb
Final flux =
A = 0 x 7.1 x 10^-4 = 0 Wb
change in flux dФ = 3.55 x 10^-4 - 0 = 3.55 x 10^-4 Wb
Induced EMF E = NdФ/dt = (17 x 3.55 x 10^-4)/2.8 = 2.15 x 10^-3 V
==> <em>2.15 mV</em>
