Question

1. which scientist was able to experimentally determine the value of the constant g?

albert einstein
lord henry cavendish
johannes kepler
sir isaac newton

Explanation:

• Albert Einstein: Known for the theory of relativity, not for determining \( G \).
• Lord Henry Cavendish: Conducted the Cavendish experiment to measure the gravitational constant \( G \).
• Johannes Kepler: Formulated laws of planetary motion, not related to \( G \) measurement.
• Sir Isaac Newton: Proposed the law of universal gravitation (\( F = G\frac{m_1m_2}{r^2} \)), but did not experimentally determine \( G \).

Answer:

Lord Henry Cavendish
