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)

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.
