Question

a concave mirror produces three times magnified real image of an object placed at 10 cm in the front of it where is the image located​

Answer 1

m = -3

u = - 10

m = -v/u

 

-3 = -v/-10

-v = -3*-10

-v = 30 cm

v = -30cm

Answer 2

Magnification= -3cm

U= -10cm

-v/u=m

V/10= -3

So,v= -30cm.
