An image of a linear object due to a convex mirror is 1/4 th of the length of the object . If focal length of the mirror is 10 cm , find the distance between the object and the image. The linear object is kept perpedicular to the axis of the mirror.

An image of an object obtained by a convex mirror is n times smaller than the object. If the focal length of lens is f, the object distance would be ...........

A man of height H is standing in front of an inclined plane mirror at an angle theta from horizontal. The vertical separation between man and inclined plane is x. Man can see its complete image in length (H(H+x)"sin"theta)/(H +2x) of mirror . (Given : x = H = 1m and theta = 45^(@) ) If man starts moving with velocity 1 ms^(-1) horizontally, find out length of mirror at t=1s in which he can see his complete image.
