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.

Explanation:

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#
