PLEASE answer questions 3 , 4 & 5. write clearly
PROBLEM 3
Calculate the magnitude of the gravitational force on a cantaloupe of mass m = 873 g on the surface
of the Earth due to
(a) the Earth
(b) the Moon
(c) the Sun
PROBLEM 4
A hypothetical planet has 1/5 of the diameter of the Earth, and its density is 4 times larger
(compared to the Earth). Find its total mass and the free fall acceleration.
PROBLEM 5
Two planets with masses M1 and M2 are located at a distance D from each other far removed from
any other planets or objects in the outer space. Where should a satellite of mass m be located if we
need to have the two gravitational forces acting on it
(a) to be balanced (equal)
(b) the force from planet M1
to be three times larger compared to that from the planet M2
