Homework Statement
Calculate, using Newton's law of gravity, the size of the force of attraction between the Earth and a mass of 3.0 kg on the Earth. Data: Distance to the center of Earth from the surface = 6370 km. Mass of Earth = 5.98 1024 kg. Gravitational constant (G = 6.67 times 10-11 Nm2/kg2).
Homework Equations
F = G(m1 * m2)/ r^2
The Attempt at a Solution
I plugged the numbers into the equation and converted km to meters and kg to g ...
6.67E-11 * (3000)(5.98E27) / (6370000)^2
and I got 2.949E-7, but it is wrong I think
