Calculate the force of gravity on earth of an object that has a mass of 200 kg.
Newton's law of universal gravitation - Wikipedia, the free encyclopedia
Substitute the values and calculate!!
Hmmm..... I read it as calculate the gravitational force of the mass that acts upon the Earth. This force will obviously depend on the distance between Earth and mass.
You read it as calculate the force of gravity of a mass that is at the surface of the Earth. I'm unconvinced. But since height is not given, you're reading of it is probably right. In which case, the wording of the question leaves (for me at least) a lot to be desired.
I'd be interested to see what topsquark makes of it. Calculate the force of gravity of a mass just doesn't do it for me ......
