    Question

    When did Henry Cavendish report the measurement of the

    gravitational constant with the mass and density of the Earth?
    A March 1795 Correct Answer Incorrect Answer
    B June 1798 Correct Answer Incorrect Answer
    C April 1796 Correct Answer Incorrect Answer
    D May 1797 Correct Answer Incorrect Answer

    Solution

    Henry Cavendish:- • He was a brilliant scientist who made significant contributions to chemistry and physics. • He discovered hydrogen in 1766 and measured the gravitational constant in 1798. • His work on the gravitational constant was particularly important, as it provided the first accurate measurement of the force of gravity between masses in the laboratory. • He reported the measurement of the gravitational constant with the mass and density of the Earth in June 1798. His results were published in a 57-page paper in the Transactions of the Royal Society entitled "Experiments to Determine the Density of the Earth."
