An object of 6cm in size is placed at 50cm in front of a convex lens of focal length 30cm. find the position,nature and size of the object.​

Answer 1

Explanation:

Given,

f = 30cm

u = - 50 cm

h = -6cm

Lens formula

1/f = 1/v - 1/u

1/v =1/f +1/u

1/v = 1/30 - 1/50

V = +75cm

m =u/v=hi/ho

75/-50=hi/6

hi = - 9 cm
