A quarter cylinder of radius \( \mathrm{R} \) and refractive index \( 1.5 \) is placed on a table. A point object \( \mathrm{P} \) is kept at a distance of \( \mathrm{mR} \) from it. Find the value of \( \mathrm{m} \) for which a ray from \( \mathrm{P} \) will emerge parallel to the table as shown in the figure.
