Question

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

Answer 1

Please find the answer in the attachment.

Answer 2

Here u = -10cm

Focal length= 15cm

We know , 1/f= 1/v + 1/u

1/15= 1/v + 1/-10

1/15 = 1/v - 1/10

1/15 + 1/10 = 1/v

2/30 + 3/30 = 1/v

5/30 = 1/v

This implies v = 6cm

The umage is virtual and erect...
