Question
In the "Current Balance" lab, you will balance a gravitational force whose strength is controlled by hanging masses, with a magnetic force whose strength is controlled by current. Based on this comparison you will...
compute a value for Newton's gravitational constant, G, then compare with the accepted value.
use the gravitational acceleration to calculate Newton's gravitational constant.
a)compute a value for Newton's gravitational constant, G, then compare with the accepted value.
b)compute a value for and then compare with the accepted value.
c)use to calculate the size of both the magnetic and gravitational forces, and then compare them directly.
d)use the gravitational acceleration to calculate Newton's gravitational constant.
Explanation / Answer
You will use this current balance to calculate the size of both the magnetic and gravitational forces, and then compare them directly. The two forces are still described by the Maxwell's equations and in relativity they can transform into each other.
