A) \[30{}^\circ \]
B) \[45{}^\circ \]
C) \[60{}^\circ \]
D) \[75{}^\circ \]
Correct Answer: C
Solution :
Suppose angle between the both mirrors is\[\theta \] Ray PQ parallel to\[{{M}_{1}}\]and ray RS parallel to \[{{M}_{2}}\] \[\angle {{M}_{1}}S=\angle ORQ=\angle {{M}_{1}}O{{M}_{2}}=\theta \] Similarly \[\angle {{M}_{2}}QP=\angle OQR=\angle {{M}_{2}}O{{M}_{1}}=\theta \] In\[\Delta OPQ\] \[3\theta =180{}^\circ \] \[\theta =60{}^\circ \]You need to login to perform this action.
