9. Find the size, nature and position of image
formed when an object of size 1 cm is
placed at a distance 15 cm from a concave
mirror of a focal length of 10 cm?
please give me answer
​

Answer 1

for concave mirror

h 1 = 1cm

u = - 15 cm

f = -10

1 / v - 1 / u = 1 / f

1/v = 1 / f + 1 / u

= 1 / -10 + 1 / -15
