Question

An object is placed at a distance of 10cm in front of a concave lens of focal length 10cm 1) find the position of the image 2) the size of the image in relation to the object. with diagram coumpalsary those who draw diagram gets brainliest​

Answer 1

Answer:

Focal length of concave mirror, f = -20 cm

Distance of object from the mirror, u = -10 cm

use formula, 1/v + 1/u = 1/f

or, 1/v = 1/f - 1/u

or, 1/v = 1/-20 - 1/-10

or, 1/v = -1/20 + 1/10 = 1/20

or, v = +20cm

hence, image position is the 20cm right side from the pole of the concave mirror as shown in the diagram. The image is straight and bigger than the object.
