Concave mirror can produce both real image as well as virtual image. But according to the given condition the concave mirror is producing real and inverted image so

ACQ-

Height =h,height of image is 3h

m=h’/h

m=-3h/h

m=-3

u=-10cm

But we know that m=-v/u

-3=-v/-10

v=-30cm

Hence solved.

Hope it will helpfull to you.

Answer 2

magnification = 4

object placed = 10cm

m = -v/u

4=-v/10

-v = 4(10)

v=-40cm
