The radius of curvature of a convex mirror is 60cm. When an object is A, its image is formed at B. If the size of image is half that of the object, then the distance between A and B is

Radius of curvature of convex mirror is 40 cm and the size of object is twice as that of image than the image distance is

If the radius of curvature of convex mirror is 40 cm and size of object is twice as that of the image,then the object distance is

A convex mirror has radius of curvature of 20 cm. An object is placed at such a distance from the mirror that the size of image is exactly half that of the object. The object must be at :-

An radius of curvature of a convex mirror is 40 cm and the size of the object is twice the size of the image. The image distance will be

Radius of curvature of concave mirror is 40 cm and the size of image is twice as that of object, then the object distance is
