A box

Explanation:

In quantum mechanics, the atom is metaphorically described as a box. In fact, the Schrödinger wave equation is based on the three dimensional box metaphor of the atom.

Thus, a box provides a convenient treatment of the atom as it represents the fundamental components of the problem of atomic structure, hence the answer.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
