1.	A small object is so placed in front of the convex lens of 5cm focal length that a virtual image is formed at a distance of 25 cm. Find the magnification.
Answer» Answer: +6 Explanation: Given: f=5 v= -25 Applying the Lens formula 1/v -1/u = 1/f 1/(-25) -1/u = 1/5 or, 1/u = 1/(-25) - 1/5 1/u = -6/25 u = -25/6 Now, MAGNIFICATION M M = v/u = (-25) / (-25/6) = +6

Answer»

Answer:

Explanation:

Given:

f=5

v= -25

Applying the Lens formula

1/v -1/u = 1/f

1/(-25) -1/u = 1/5

or, 1/u = 1/(-25) - 1/5

1/u = -6/25

u = -25/6

Now, MAGNIFICATION M

M = v/u

= (-25) / (-25/6)

= +6
