    A particle is projected horizontally from the top of a cliff of height H with a speed\[\sqrt{2gh}\] . The radius of curvature of the trajectory at the instant of projection will.

    A)  \[H/2\]                        

    B)  \[H\]

    C)  \[2H\]                         

    D)  \[\propto \]

    Correct Answer: D

    Solution :

    Since   \[g\bot \upsilon \] Radial acceleration \[{{a}_{r}}=g\] \[\Rightarrow \]               \[\frac{\upsilon _{0}^{2}}{r}=g\] Where, r is the radius of curvature             \[\frac{2g\,H}{r}=g\]    \[(\therefore \,\,\upsilon =\sqrt{2g\,H})\]                 \[r=2H\]
