Answer to Problem 1OQ

Solution:

c. Electric forces.

Explanation of Solution

We will discuss each of the options.

  1. Gravitational force

    Since the mass of the atoms of the solid is very small, the effect of gravitational force is very weak to hold them together.
  2. Magnetic force

    The magnetic field processed by most of the atoms are very small, hence magnetic force cannot hold the atoms of the solid together.
  3. Electric force

    The electric force due to the exchange and sharing of the electron in an atom can hold the atoms in a solid together.
  4. Glue

    Glue is not at all an option for holding the atoms together.
  5. Nuclear force

    Nuclear force holds the particle inside nuclei together but does not act on the molecular level.

Conclusion:

c. Electric force

The electric force due to the exchange and sharing of electron holds the solid together.
