A concave mirror of radius 40cm lies on a horizontal table and water is filled in it upto a height 5cm.A small dust particle floats on th 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 1.3

Dear Cheekorita, you are right, but the focal length of a spherical mirror is approximately half its radius of curvature. So the answer is ok.
How has 2/R came in mirror formula....isn't the mirror formula 1/v+1/u=1/f
