A satellite moves at a constant speed in a circular orbit about the center of the Earth at an altitude half the radius of the Earth above its surface. if 'g' is the
gravitational acceleration at the surface of the Earth and Rits radius, then what
will be the speed of the satellite?
O V25R
123R/3
133R/2
VOR

Explanation:

Using the gravitational force equation

D is the distance from the center of the earth

Now, we can equal this equation to the centripetal force.

V is the speed of the satellite

But if we evaluate the force at the surface of the earth we have:

Then we can use this expression into the equation of V
