Question

an object is placed at a distance of 10cm front a concave mirror of focal length 15cm find the position and nature of image​

Answer 1

Answer:

v = -30cm and its a real and inverted image

Explanation:

u = - 10cm

f = - 15cm

v = ?

1/v + 1/u = 1/f

1/v = 1/f - 1/u

= 1/-15 - 1/-10

= -15 - (- 10)/150

= -5/150

v = -30cm

m = -v/u

= -30/10

m = -3cm
