Question

On earth, two parts of a space probe weigh 13500 N and 7000 N. These parts are separated by a center-to-center distance of 15 m and may be treated as uniform spherical objects. Find the magnitude of the gravitational force that each part exerts on the other out in space, far from any other objects.

Answer 1

F(grav)= Gm1m2/r^2. G=universal grav. constant, r=15m , m1=1350 kg and m2=700kg.

Answer 2

that's assuming g=10m/s^2 , you probably shouldn't .

Answer 3

no , the above's newton's law of gravitation for 2 bodies..nowhere does it involve the earth..

Answer 4

here since weight/force is given, it does involve gravity/acceleration due to gravity

In the formula, m1 and m2 are masses and not weight/force

so first their masses have to be calculated....
