acc mirror Formula 1/u+1/v=1/f. so, =(-1/10)+-(1/6 ) f=15
wafikhan:
thankyou
I think so you should take +1/6
I am not saying u r wrong I am just giving my point of view
ok
since image is formed in front of a mirror ie. real, so i have taken - 1/6
ohk
sorry to intrupt in between
there is no need of sorry, I want only reason.
ohk

U= - 10
V= -6
1/u +1/v =1/f
_1/10+(-1/6) =1/f
1/f = - 16/60
1/f = - 4/15
f = - 15/4m
V= -6
1/u +1/v =1/f
_1/10+(-1/6) =1/f
1/f = - 16/60
1/f = - 4/15
f = - 15/4m
wrong
how
