    A body, thrown upwards with some velocity reaches the maximum height of 50 m. Another body with double the mass thrown up with double the initial velocity will reach a maximum height of

    A)                  100 m                                  

    B)                  200 m

    C)                  300 m                                  

    D)                  400 m

    Correct Answer: B

    Solution :

                    Key Idea : At maximum height, final velocity is zero. From equation of motion, we have                 \[A(x=0)\] where v is final velocity, u is initial velocity, h is height and g is acceleration due to gravity. Since, body reaches maximum height in both cases, hence final velocity is zero. \[C(x=5),\]          \[\therefore \] \[y=a\cos (\omega t-kx)\]           \[(\omega t-kx)\] Given, \[[k]=\frac{1}{[x]}=\frac{1}{[L]}\] Note: Maximum height attained does not depend upon the mass of the body.
