# Mini-Quiz: Similarity Between Gravitation and Electrostatic Forces

by Ron Kurtus (5 December 2010)

Take this Mini-Quiz to check your understanding of the lesson material.

1. How are the gravitation and electrostatic for equations parallel?

They are in the same form but with different variables

Either one could be used when making calculations

Both are dependent on the mass of the objects

2. What might allow anti-gravitation?

Increasing the mass of each object

Reduction in electrical charge

Dark energy

3. What does gravitomagnetism predict would happen to a free-falling marble near the Sun?

The marble would burn up, due to the Sun's heat

The marble should start to spin due to the Sun's rotation

The marble would be repelling into space, due to the Sun's anti-gravity

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.

Look at various similarities in science
