Answer:
answer 2 :
given
height of object = 5 cm
position of object ,u = 25 cm
focal length of object, f = 10 cm
position of image, v = ?
we know that,
1/v -1/u = 1/f
1/v +1/25= 1/10
1/v = 1/10-1/25
So,
1/v = (5-2)/50
that is ,
1/v = 3/50
So,
v= 50/3 = 16.66 cm
Thus, distance of image is 16.66 cm on the opposite side of lens .
