A real object is placed in front of a convex mirror (fixed).The object is moving toward the mirror. If `v_(0)` is the speed of object and `v_(i)` is the speed of image, then

Options

A. `v_(i) lt v_(0)` always
B. `v_(i) gt v_(0)` always
C. `v_(i) gt v_(0)` initially and then `v_(0) gt v_(i)`
D. `v_(i) lt v_(0)` initially and then `v_(i) gt v_(0)`

Answer

A

Explanation

As object moves from infinity to the pole of convex mirror, image moves from focus to pole. So `v_(i) lt v_(0)` , always.
