Question

Write the position and nature of the image formed when the object is kept
at a distance of 10 cm from a convex lens. (Focal length=5 cm) [5]​

Answer 1

Answer:

focal length=40 cm

u=-10

lens formula

1/f=1/v-1/u

1/v=1/f+1/u

1/v=1/40+1/-10

=1/40-1/10

=1-4/40

=-3/40

or v=13.33 cm

thus position of image =The image gets formed at 13.33 cm on the oppsosite side of lens

negative sign indicates that the image formed is inverted

thus nature of image=real and inverted.
