    When a coin and a feather are dropped simultaneously from the same height, the coin strikes the ground first. Why?

    A)  Gravitational force is less in the case of the coin.

    B)                         Mass of coin is less.

    C)                         Frictional force is less in the case of the coin.

    D)                         Magnetic force is stronger in the case of the coin.

    Correct Answer: C

    Solution :

    Due to larger surface area, the feather faces more air resistance (friction by air) and hence slows down, while the coin moves faster and touches the ground faster.
