the gravitational constant g was first measured accurately by henry cavendish in 1798. he used an exquisitely sensitive balance to measure the force between two lead spheres whose centers were 0.19 m apart. one of the spheres had a mass of 138 kg, while the mass of the other sphere was 0.93 kg.

Respuesta :

The answer is

3.5*10^-8:1

Explanation:

F(gravitation) = G*M1M2/r^2

G = gravitational constant = 6.67*10^-11 Nm^2/kg^2

M1 = mass of the heavier sphere,

M2 = mass of the lighter sphere

r = their distance apart

Fg = 6.67*10^-11*188*0.93/(0.19)^2

Fg = 3.23*10^-7N

The ratio of the force of gravitation between them to the weight of the lighter sphere = 3.23*10^-7: (0.93*9.81) = 3.5*10^-8. : 1 by dividing both side by (0.93*9.81)
