A) \[\frac{{{R}^{2}}}{2}\]
B) \[{{R}^{2}}\]
C) \[\frac{3{{R}^{2}}}{2}\]
D) \[4{{R}^{2}}\]
Correct Answer: B
Solution :
[b] \[\tan \theta =\frac{R}{L}\] \[CP.CQ=\left( \sqrt{{{R}^{2}}+{{L}^{2}}} \right)\times R\sin \theta \] \[=\left( \sqrt{{{R}^{2}}+{{L}^{2}}} \right)\times R\times \frac{R}{\sqrt{{{R}^{2}}+{{L}^{2}}}}={{R}^{2}}\]You need to login to perform this action.
