Answer:

The magnitude of the force of gravity on that person is 784 Newton.

Step-by-step explanation:

The weight is a force acting on an object as a consequence of gravity and is defined as:

$W = m \cdot g$ (1)

Where m is the mass and g is the value of the gravity.

Finally, making the assumption that the person is in the Earth and using equation 1 it is gotten:

W = (80.0 kg)(9.8m/s^(2))

Remember that the value of g change in function of the radius and mass of the planet ({tex]g = \frac{G\cdotM}{R^{2}}[/tex])

W = 784 Kg.m/s^(2)

But
1 N = kg.m/s^(2)

W = 784 N

Therefore, the magnitude of the force of gravity on that person is 784 Netwon.
