Question

an object of 5 metres in length is placed at a distance of 20 CM in front of a convex mirror of radius of curvature 30cm find the position of the image in its nature and size

Answer 1

H =500 cm

U=-20 cm

F= 15 cm

Mirror formula

1/f =1/v+1/u

1/15 = 1/v-1/20

1/v= 7/ 60

V= 60/7

H'/h=(-v) /u

H'= 21.4 cm

Nature virtual and inverted
