Answer:
ANSWER
It is to be remembered that a convex mirror always forms the virtual, erect and diminished image.
Given: Object distance, u=−10cm Focal length, f=15cm
To find: Image distance, v
From mirror formula :
v
1
+
u
=
f
−
10
15
150
25
v=6cm
Hence image will be formed 6 cm beyond the mirror, i.e virtual magnification
m=
−v
−10
−6
=0.6
Explanation:
distance at which the object is placed=10cm
image formed=15cm
focal length=I/2*radius
=1/2*7.5
7.5/2cm is the answer
