The universal gravitational constant is determined in which way?
ATraditionally
BAutomatically
CExperimentally
DAlphabetically
Answer & Solution
Correct answer: C. Experimentally
1. The constant cannot be derived from the other laws of motion.
2. Its value has to be measured in a laboratory.
3. The universal gravitational constant is determined experimentally.
4. Cavendish made that measurement using two ordinary-sized masses.
