An object of length \( 2.5 \mathrm{~cm} \) is placed at a \( 1.5 \mathrm{f} \) from a concave mirror where \( \mathrm{f} \) is the magnitude of the focal length of the mirror. The length of the object is perpendicular
\( \mathrm{P} \) to the principal axis. Find the length of the image. Is the image erect or inverted?

(A) \( -8 \mathrm{~cm} \)
(B) \( -10 \mathrm{~cm} \)
(C) \( -5 \mathrm{~cm} \)
(D) \( -12 \mathrm{~cm} \)
