    If the mass of the Sun were ten times smaller and the universal gravitational constant were ten times larger in magnitude, which of the following is not correct?                              [NEET - 2018]

    A) Time period of a simple pendulum on the Earth would decrease

    B) Walking on the ground would become more difficult

    C) Raindrops will fall faster

    D) 'g' on the Earth will not change

    Correct Answer: D

    Solution :

    [d] If Universal Gravitational constant becomes ten times, then \[\text{G }\!\!'\!\!\text{ =10G}\]
    So, acceleration due to gravity increases.
    i.e. [d] is wrong option.
