# Mini-Quiz: Derivation of Gravitational Constant from Cavendish Experiment

by Ron Kurtus (20 February 2015)

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

1. How does the torque from the wire relate to the angle turned?

It is proportional to the angle turned

It has nothing to do with the angle turned

It is inversely propositional to the angle turned

2. Why must the torsion coefficient be derived?

It puts the equation in terms of newtons

To measure the angle and oscillation period

It cannot be measured by the experiment

3. What are two major factors in finding the torsion coefficient?

Angle and mass of balls

Oscillation period and moment of inertia

Equilibrium angle and oscillation period

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.
