The capacitance is given by
Answer:
Option D: 1.5in in front of the target
Explanation:
The object distance is .
Because the surface is flat, the radius of curvature is infinity .
The incident index is and the transmitted index is
.
The single interface equation is
Substituting the quantities given in the problem,
The image distance is then
Therefore, the coin falls in front of the target
