Given that,
u=-12cm , v=?
f=+30 cm we know that
1/f=1/u + 1/v
1/v=1/30 + 1/12
1/v=7/60
v=60/7 cm
Now,
m=-v/u
m=-60/-12×7
m=5/7
Location=60/7cm behind mirror
Magnification=5/7
u=-12cm , v=?
f=+30 cm we know that
1/f=1/u + 1/v
1/v=1/30 + 1/12
1/v=7/60
v=60/7 cm
Now,
m=-v/u
m=-60/-12×7
m=5/7
Location=60/7cm behind mirror
Magnification=5/7

Explanation:
u=-12cm
v=?
f=30cm
1/f=1/u+1/v
1/v=1/30+1/12
1/v=7/60
magnification formula
m=-v/u
m=-60/12×7
m=5/7
