Focal length of convex mirror, f = +15 cm
Object distance, u = −10 cm
According to the mirror formula,
`rArr1/v=1/f-1/u`
`rArr1/v=1/15-1/(-10)`
`rArr1/v=1/15+1/10`
`rArr=(2+3)/30`
`rArr=5/30`
`rArrv=6 cm`
`"Magnification"=(-v)/u=(-6)/-10=0.6`
The image is located at a distance 6 cm from the mirror on the other side of the mirror.
The positive and less than 1 of magnification indicates that the image formed is virtual and erect and diminidhed.
