  • If the sun and the planets carried huge amounts of opposite charges, a) all three of Kepler’s laws would still be valid b) only the third law will be valid c) the second law will not change

If the sun and the planets carried huge amounts of opposite charges,

a) all three of Kepler’s laws would still be valid

b) only the third law will be valid

c) the second law will not change

d) the first law will still be valid

Answers (1)

The correct answer is the option (a), (c), and (d). Due to opposite charges, large electrostatic forces of attraction will be produced in addition to the gravitational forces. Both forces, when added, will be radial in nature. Since they are central forces and obey inverse square law, all 3 Kepler's laws will be valid.
