A man with a mass of 80 kg is standing on the surface of the earth. Calculate the magnitude of the attractive force that the earth exerts on the man (784N)
1 answer
The magnitude of the attractive force that the earth exerts on the man is 784N. This can be calculated using the equation F = G * m1 * m2 / r^2, where G is the gravitational constant (6.67 x 10^-11 Nm^2/kg^2), m1 is the mass of the man (80 kg), m2 is the mass of the earth (5.98 x 10^24 kg), and r is the radius of the earth (6.37 x 10^6 m). Plugging these values into the equation gives us F = 784N.
