A) \[\frac{1}{\sqrt{3}}\,\,meter\]
B) \[\frac{1}{3}\,\,meter\]
C) \[\sqrt{3}\,\,meter\]
D) \[3\,\,meter\]
Correct Answer: A
Solution :
Let \[AB=1\text{ }m\] be the stick. Let AC be the shadow of length x. From right angled \[\Delta \,ACB,\] \[\tan \,{{60}^{o}}=\frac{1}{x}\] or \[\sqrt{3}=\frac{1}{x}\] or \[x=\frac{1}{\sqrt{3}}m\]You need to login to perform this action.
