A) \[{{1.43}^{o}}\]
B) \[{{0.72}^{o}}\]
C) \[{{0.0125}^{o}}\]
D) \[{{0.025}^{o}}\]
Correct Answer: A
Solution :
Let angle subtended by coin at the eye be 6. \[\sin \theta \simeq \frac{D}{L}\] Here, \[D=2r=2\times 1=2\,\,cm\] \[L=80\,\,cm\] \[\therefore \] \[\theta =\frac{2}{80}=0.025\] rad \[={{1.43}^{o}}\]You need to login to perform this action.
