A) \[\frac{p-\delta }{p+\delta }\]
B) \[\frac{p+\delta }{p-\delta }\]
C) \[\sqrt{\frac{p}{\delta }}\]
D) \[\sqrt{\frac{\delta }{p}}\]
Correct Answer: A
Solution :
From figure \[\delta gR\left( cos \theta + sin \theta \right) =PgR\,(cos\theta - sin \theta )\] \[\Rightarrow \,\,\,\,\,\,\,\,\,\,\sin \theta \left( \delta +P \right)\,\,=\,\,cos\theta \left( P-\delta \right)\] \[\Rightarrow \,\,\,\,\,\,\,\,\,\,\tan \theta =\frac{P-\delta }{P+\delta }\]You need to login to perform this action.
