Answer 1

Answer #1

Solution)

Given,

Image distance, i=-14.5 cm

Focal lengtj, f= -19.5 cm

We know,

1/f= 1/i+ 1/o

Substitute values,

1/(-19.5)=1/(-14.5) +1/o

We have object distance, o= 56.6 cm -----option d (Ans)

========

draw a ray diagram for this If a virtual image is formed along the principal axis 10.0 cm from a concave mirror with the focal length 15.0 cm, what is the object distance from the mirror? Use the mirror equation: 1/di + 1/do = 1/f where di = -10 cm and f = +15 cm. (Note that di is negative if the image is virtual.) Substitute and solve for do. 1/do + 1/(-10 cm) = 1/(15 cm) 1/do = 1/(15...
