A spherical surface separates two media of refractive indices $\displaystyle 1$ and $\displaystyle 1.5$ as shown in figure.
Distance of the image of an object ' O ', is :
( $\displaystyle C$ is the center of curvature of the spherical surface and $\displaystyle R$ is the radius of curvature)Official answer
From NTA’s final answer key for this paper.
(1)
0.$\displaystyle 4$ m left to the spherical surface
