HEY MATE
A/Q
GIVEN
F = 15CM
V = 10 CM
U= ?
AND IN CONVEX LENS
V, F ARE = + ve
and U = - ve
BY USING LENS FORMULA
1/V-1/U=1/F
1/U=1/F-1/V
1/U= 1/15-1/10
1/U= 2-3/30
1/U = -1/30
U = -30
AND MAGNIFICATION = V/U
= 10/-30
= 1/-3
I HOPE THIS WILL HELP YOU...
PLS MARK AS BRAINLIEST.

Ritvish:
I think you have written it wrong
1/v-1/f=1/u
no bro lens formula is 1/v-1/u=1/f is correct.
Just see your 12th line
You have written 1/u=1/f-1/v
It should be -1/u=1/v-1/f
Moreover I think that this Question is incorrect
u is already in minus so -1/-u= 1/u so anything more?
and 1/v go right side so I done it correctly bro
