Answer 2

Dear Student,

◆ Answer -

Image is formed 60 cm to the right and is real, inverted and magnified.

● Explanation -

# Given -

u = -30 cm

f = 20 cm

# Explanation -

Using lens formula -

1/f = 1/v - 1/u

1/20 = 1/v - 1/(-30)

1/20 = 1/v + 1/30

1/v = 1/20 - 1/30

1/v = 1/60

v = +60 cm

Hence, image is formed 60 cm to the right and is real, inverted and magnified.

Thanks dear. Hope this helps you...
