1.	A point object is kept at the first focus of convex lens ,if the lens starts moving towards right will a constant velocity,th image will A. always move towards rightB. always move towards leftC. first move towards right &then towards leftD. first move towards left &then towards right
Answer» Correct Answer - D `(dv)/(dt)=((v)/(u))^(2)xx(du)/(dt)` `V_("image/lens")=((v)/(u))^(2)xxV_("object/lens")` till `u` become `2f mgt-1"so" V_("image/lens")gtV_("object/lens")` and image will moves towards left and when `u "become" gt 2fV_("image/lens")ltV_("object/lens")`and image will moves towards right.
