A) 2.0
B) 2.5
C) 1.6
D) 1.5
Correct Answer: D
Solution :
When viewed from face (1) \[\mu =\frac{u}{v}=\frac{x}{v}\]\[=\frac{x}{6}\] .....(i) Now when viewed from face (2) \[\mu =\frac{15-x}{v}=\frac{15-x}{4}\] .....(ii) From equation (i) and (ii) \[\mu =\frac{15-6\mu }{4}\]\[\Rightarrow \mu =1.5\].You need to login to perform this action.
