2 A is a thin walled sphere at rest made up of glass The radius of the sphere is Im and it is filled with a transparent liquid of refractive index S is the luminous source moving directly towards a plane vertical mirror M A fish in the liquid is moving towards S The eye of the fish and S and collinear perpendicular to mirror M At the instant shown S is 3m away from the center of the sphere fish observes that image of S due to reflection is moving with speed of 13m s If speed of the fish relative to the sphere is 10m s and 1 5 then find the speed of the source at that instant The system is placed in air Fish THE NARA GR A GROUP
