A concave mirror of radius 40 cm lies on a horizontal table and water is filled in it upto a height of 5.00 cm. A small dust particle floats on the water surface at a point P vertically above the point of contact of the mirror with the table. Locate the image of the dust particle as seen from a point directly above it. the refractive index of water is 1.33.
