Question

a concave mirror of focal length is 10cm produces an image 5 times larger and real the distance of object from the mirror will be​ ..

Answer 1

Answer:

-12cm

Step-by-step explanation:

f = -10cm

M = 5

v/u = 5

v = 5u

By mirror formula:

1/f = 1/v + 1/u

1/f = 1/5u + 1/u

1/f = 6/5u

f= 5u/6

u= 6f/5

u= 6(-10)/5

u = -12cm
