Question

#38

Using 6,370 km for Earth's radius, compare the gravitational
force acting on a NASA rocket when it is sitting on its launch-
pad with the gravitational force acting on it when it is orbit-
ing 350 km above Earth's surface.

Expert Solution

Step 1

We know that

F= $G \frac{m M}{r^{2^{}}}$

G= gravitational constant

m= mass of the NASA rocket

M= mass of earth

r= distance between them
