JEE Main & Advanced Physics Gravitation / गुरुत्वाकर्षण Question Bank Acceleration Due to Gravity

  • question_answer
    The acceleration of a body due to the attraction of the earth (radius R) at a distance 2 R from the surface of the earth is (g = acceleration due to gravity at the surface of the earth) [MP PET 2003]

    A)             \[\frac{g}{9}\]

    B)             \[\frac{g}{3}\]

    C)             \[\frac{g}{4}\]

    D)             g

    Correct Answer: A

    Solution :

                                \[g'=g\,{{\left( \frac{R}{R+h} \right)}^{2}}=g\,{{\left( \frac{R}{R+2R} \right)}^{2}}=\frac{g}{9}\]
