and a plane mirror will be equal to -
(a) 50 cm
(b) 100 cm
lle
(c) 0 cm
(d) infinite
e 17 (v) Suppose the distance of one object from the above mirror is equal to the radius of
curvature of the mirror. Then which of the following statement is correct regarding the
nature and size of the image formed.
