In our solar system, the inter-planetery region has chunks of matter (much smaller in size compared to planets) called asteriods. They

A

Will not move around the sun, since they have very small masses compared to the sun

B

Will move in an irregular way because of their small masses and will drift away into outer space

C

Will move around the sun in closed orbits but not obey Kepler’s laws

D

Will move in orbits like planets and obey Kepler’s laws

Text Solution

Verified by Experts

The correct Answer is:
D
Asteroids are also being acted upon by central gravitational forces, hence they are moving in circular orbits like planets and obey Kepler’s laws.

Our solar system has __________ planets.

A: Bohr's model with its planet - like electron is not applicable to many electron atoms. R: Unlike the situation in the solar system, where planet-planet gravitational forces are very small as compared to the gravitational force of the sun on each planet, the electron electric force interaction is comparable in magnitude to the electron nucleus electric force.
