An erect and enlarged image can be formed by
(a) only a convex mirror.
(b) only a concave mirror.
(c) only a plane mirror.
(d) both convex and concave mirrors.
Here, in case of concave mirror
u=10 cm [u, is always negative]
v =?;m = - 3 [real image]
Now the magnification formula is
m= -v/u or -3= -(v/-10)
or , v = -30 cm.
Image will...
The image formed by a concave mirror is virtual, erect and larger only when the object is placed between the pole of the mirror and its principal focus. So correct...
