A) \[2\,\pi \,{{r}^{2}}/T\]
B) \[\upsilon ,\,\upsilon \text{ and }\upsilon \]
C) \[2h\]
D) \[3h\]
Correct Answer: C
Solution :
[c] For greatest height \[\theta =90{}^\circ \] \[{{H}_{\max }}=\frac{{{u}^{2}}{{\sin }^{2}}(90{}^\circ )}{2g}=\frac{{{u}^{2}}}{2g}=h\] (given) \[{{R}_{\max }}=\frac{{{u}^{2}}{{\sin }^{2}}2(45{}^\circ )}{g}=\frac{{{u}^{2}}}{g}=2h\]You need to login to perform this action.
