Trick::M=f/f-u....and this is the simplest formula u can find with magnification and this formula is available only on coaching centers.but so many board students didn't know..hope u get answer

Answer 2

Answer:

Image is real and inverted, diminished and height of image =15/16

Explanation:

hobject= 5cm

u= -2cm

f= -30cm

using mirror formula

v=15/7

Since, m= -f/(f+u)

Therefore, m= -15/16

Now, -hobject/himage = -15/16

Therefore, himage = 16/3
