A) \[19.09\]cm from the pole of the concave mirror
B) \[19.09\]cm from the pole of the convex mirror
C) \[11.09\]cm from the pole of the concave mirror
D) \[11.09\] cm from the pole of the convex mirror
Correct Answer: A
Solution :
[a]For convex mirror: |
\[\frac{1}{v}+\frac{1}{-30}=\frac{1}{+15}\] |
Or \[v=10m\] |
For concave mirror: |
\[\frac{1}{v}+\frac{1}{-70}=\frac{1}{-15}\] |
Or \[v=-19.09\operatorname{m}\] |
