A point object is placed at a distance of 0.3m from a convex lens ( f=0.2m) cut into 2 halves each of which is displaced by 0.0005m . Lower half is rotating about its centre with angular velocity Pi-radian per second and the medium between 2 halves is vertically half filled by water of refractive index 4/3 and rest half by ether of refractive index 21/2 .
Find the position, magnification and angular velocity of image.
