An object is placed in front of a convex mirror at 60 m from the mirror. Its radius of curvature is 40 m. The object starts moving towards the mirror at 20 m/s. Then the average speed of the image after a time interval of 2 sec is ___ m/s.

Q. An object is moving with velocity v towards a stationary plane mirror. If mirror starts moving towards the object with speed v, the speed of the image of the object

A real object is placed in front of a convex mirror (fixed). The object is moving towards the mirror. If V0 is the speed of the object and Vi be speed of image, then

The correct option is A Vi<V0 always As object moves from infinity to pole of convex mirror, image moves from focus to pole. So, vi<v0 always

A real object is placed in front of a convex mirror (fixed). The object is moving towards the mirror. If $V_{0}$ is the speed of the object and $V_{i}$ be speed of image, then

The correct option is A $V_{i} < V_{0}$ always

As object moves from infinity to pole of convex mirror, image moves from focus to pole. So, $v_{i} < v_{0}$ always
