Question 17: Gravitation

Question

The value of universal gravitational constant was first determined by

Accepted Answer

The universal gravitational constant G first got its measured value from Henry CavendishÃ¢ÂÂs torsionÃ¢ÂÂbalance experiment in 1798.
Ã¢ÂÂ¢ Newton formulated the law
$$F = G\,\frac{m_1\,m_2}{r^2}$$
but never measured G himself.
Ã¢ÂÂ¢ Galileo studied falling bodies, not gravitational attraction between masses.
Ã¢ÂÂ¢ Einstein revised our understanding of gravity, but he didnÃ¢ÂÂt determine GÃ¢ÂÂs value.
