here, u=20 cm
& f=25 cm
using mirror formula
1/f = 1/v + 1/u
1/25 = 1/v+ 1/20
1/v = 1/25 - 1/20
1/v = -1/100
v = -100 cm
nature of image is real & inverted
because v is negative
& f=25 cm
using mirror formula
1/f = 1/v + 1/u
1/25 = 1/v+ 1/20
1/v = 1/25 - 1/20
1/v = -1/100
v = -100 cm
nature of image is real & inverted
