Chapter 32, Problem 2RAT

The solar system is like an atom in that both

(a) are governed principally through the electric force.

(b) consist of a central body surrounded by objects moving in elliptical paths.

(c) are composed of plasma.

(d) are mainly empty space.

To determine

The correct option for the statement “The solar system is like an atom in that both”

Answer to Problem 2RAT

The correct option for the statement “The solar system is like an atom in that both” is option (b).

Explanation of Solution

In the solar system, the planets are bound to the Sun by the gravitational forces of attraction. All the planets revolve around in elliptical orbits.

On the other hand, the electrons also revolve around the nucleus in an elliptical orbit. The electrons are bound to the nucleus by the electrostatic force of attraction. The only similarity the atomic structure is having with the solar system is that there is a huge mass at the center.

For the solar system, the huge mass at the center is Sun and for the atomic structure, the huge mass at the center is mass of the nucleus.

Conclusion:

Therefore, the correct option for the statement “The solar system is like an atom in that both” is option (b).
