Vedclass · Answer

(A) Given: Focal length of the concave mirror $f = -20\;cm$. Object distance $u = -40\;cm$.Since the object is placed at a distance of $40\;cm$ from the mirror,and the radius of curvature $R = 2f = 2 	imes 20 = 40\;cm$,the object is placed at the centre of curvature $(C)$.According to the rules of image formation by a concave mirror,when an object is placed at the centre of curvature,the image is formed at the same position.The image formed is real,inverted,and of the same size as the object.
