<span>Since the gravitational field at that altitude is known, we can simply find the force exerted by multiplying the strength of that field by the mass of the object with which it is interacting, in this case the student (who is presumably in space). So, we multiply 7.51 n/kg * 54 kg to yield a force of attraction of 405.54 n.</span>
