Question

The easy measurement of g=9.81 m/s², in the laboratory, already provides us with the information about the product GM_E (where G is the gravitational constant and M_E the mass of Earth), if the Radius R_E, of Earth is known, given that g=GM_E/R_E².

a) (15 p) The Radius of Earth, can be easily measured. And, how would you do it? Explain briefly.

b) (15 p) How would you measure g, chronometering the loss of altitude of an object, assumed free of friction, in a free fall?
