The speed of rain is
A) \[\frac{{{\eta }^{2}}}{4g{{a}^{2}}}\]
B) \[{{t}_{1}}\]
C) \[{{t}_{2}}\]
D) \[2g({{t}_{1}}+{{t}_{2}})\]
Correct Answer: B
Solution :
Velocity of man is \[{{\gamma }_{1}}\] \[{{\gamma }_{2}}\] Velocity of rain w.l.to man is \[\frac{{{\gamma }_{1}}-{{\gamma }_{2}}}{3}+\frac{\alpha }{3}\] or, \[\frac{{{\gamma }_{1}}-{{\gamma }_{2}}}{2}+\alpha \] or, \[\frac{{{\gamma }_{1}}-{{\gamma }_{2}}}{3}+3\alpha \] \[\frac{{{\gamma }_{1}}-{{\gamma }_{2}}}{3}+\alpha \] \[{{E}_{I}}>{{E}_{II}}>{{E}_{III}}>{{E}_{IV}}>{{E}_{V}}\] \[{{E}_{I}}>{{E}_{III}}={{E}_{V}}\,and\,\,\,{{E}_{II}}>{{E}_{IV}}\]
