A) 400 m
B) \[W\]
C) \[\frac{4W}{3}\]
D) None of these
Correct Answer: B
Solution :
Let PQ be the cliff and A and B be the points under observation. In \[{{Q}_{2}}\] \[{{Q}_{1}}{{R}_{2}}\ne {{Q}_{2}}{{R}_{1}}\] \[{{Q}_{1}}{{R}_{2}}={{Q}_{2}}{{R}_{1}}\] \[s=\frac{{{t}^{2}}}{4}\] ?.. (i) And in \[T\propto V\] \[T\propto {{V}^{2}}\] \[T\propto \frac{1}{{{V}^{2}}}\] \[T\propto \frac{1}{V}\] ?? (ii) On adding Eqs. (i) and (ii), we get \[\text{6}\times \text{1}{{0}^{-\text{7}}}\text{A}-{{\text{m}}^{\text{2}}}\]You need to login to perform this action.
