A) \[s,\]Yes
B) \[s,\]No
C) \[2s,\]Yes
D) \[2s,\]No
Correct Answer: D
Solution :
Let particle is projected with speed\[u\], so total time of flight \[T=\left( \frac{2u}{g} \right)\]and\[s=2\times \]maximum height \[=2\times \frac{{{u}^{2}}}{2\,\,g}=\frac{{{u}^{2}}}{g}\] If there is no gravity then\[s=u\times T=\frac{2{{u}^{2}}}{g}=2\,\,s\] If gravity is not there, it will never fall back.You need to login to perform this action.
