Virtually the same. Weight is just the force mass feels in the presence of another mass. The change in distance is trivial, given the size of the earth’s radius.


Newton’s law of universal gravitation is #F = -G.(m_1.m_2)/r^2# where G is the gravitational constant and the minus sign just shows the force vector points in the opposite direction to the radius vector.

I get 14.66N, taking the mass of the Earth as #6xx10^24# kg and G as #6.67xx10^-11 Nm^2kg^-2#
