Solution

The correct option is C π36 m
Given,
Distance of the object from the prism (a)=2 m
Angle of the thin prism (A)=5
Refractive index of the prism (μ)=1.5

We know that the shift (S) produced by the thin prism is given by :
S=a(μ1)A
Putting the values given in the question.
S=2×(1.51)×5×π180
S=π36 m

Hence, option (c) is the correct answer.
