Expert Solution

Step 1

The gravitational force on Earth is equivalent to the force which the Earth exerts on you.

$\begin{array}{rcl} M a s s & = & \frac{w e i g h t o n e a r t h}{g r a v i t a t i o n a c c e l e r a t i o n} \\ = & \frac{655}{9.8} \\ = & 66.83 k g \end{array}$

Gravitational force is given as,

$F_{g} = G \frac{M \times m}{r^{2}}$

where G is gravitational constant and m and M are masses and r is the distance
