f = +15 cm,

u = -10 cm

1/f = 1/v +1/u

1/v = 1/15 +1/10

1/v = 5/30

v = + 30 cm

The image is formed 6 cm behind the mirror; it is a virtual and erect image

Answer:

<body bg color=white><marquee scrollamount="3" direction="up"><font color=black>

f =  + 15 \: cm

u =  - 10 \: cm

 \frac{1}{f}  =  \frac{1}{v}  +  \frac{1}{u}

 \frac{1}{v}  =  \frac{1}{15}  +  \frac{1}{10}

 \frac{1}{v}  =  \frac{5}{30}

v =  + 30 \: cm
