A) 1 m
B) 2
C) 3 m
D) 4 m
Correct Answer: C
Solution :
Triangles QBR and BOA are similar, hence, \[{{v}_{T}}=\frac{4}{3}\,\pi \frac{{{R}^{2}}\rho g}{k}\] or \[{{C}_{4}}{{H}_{10}}O\] \[C{{H}_{3}}-C{{H}_{2}}-C{{H}_{2}}-C{{H}_{2}}OH\] Height of the building which can be observed in the mirror from point O, \[C{{H}_{3}}-C{{H}_{2}}-\underset{\begin{smallmatrix} | \\ OH \end{smallmatrix}}{\mathop{C}}\,H-C{{H}_{3}}\]You need to login to perform this action.
