Question

    If radius of earth is R then the height ‘h’ at which the value of ‘g’ becomes one-fourth is-

    A R Correct Answer Incorrect Answer
    B 2R Correct Answer Incorrect Answer
    C 3R Correct Answer Incorrect Answer
    D 4R Correct Answer Incorrect Answer

    Solution

    With height g’= g/(1+h/R) Since, g’=g/4 Hence, putting the value of ‘g’ in the equation- We get, g=R
