Answer 2

Dear Student,

◆ Answer -

Image position = 6 cm behind mirror

Image nature = Virtual, erect and diminished

● Explanation -

# Given -

f = +15 cm

u = -10 cm

# Solution -

According to mirror formula -

1/f = 1/u + 1/v

1/15 = 1/-10 + 1/v

1/v = 1/15 + 1/10

1/v = 2/30 + 3/30

1/v = 5/30

v = 6 cm

Therefore, image formed at 6 cm behind the mirror and will be virual, erect and diminished.

Thanks dear.
