Answer 2

Focal length (f) 15 cm

Distance of object from the convex

mirror (u) 10 cm

Image distance (v) = ?

1/v-1/u = 1/f

1/ 1/5+1/10

/v = 2 + 3 /30 (whole by L.C.M)

1/v = 5/30

v=6cm

Image distance = 6 cm

Image distance is in positive, thus the

image is formed behind the mirror, thus

it's VIRTUAL and ERECT.
