Question

* An object placed at a distance of 5m from a convex mirror of focal length 1.5m find the position and Nature of the object.​

Answer 1

Answer:

According to the question:

Focal length, f=−1.5 m (Since it is a concave mirror)

Object distance, u=−40 cm=−0.4 m (Since 1 m=100 cm)

By mirror formula:

v1+u1=f1[4pt]

⇒v1+−0.4 m1=−1.5 m1[4pt]

⇒v1=0.4 m1−1.5 m1[4pt]

⇒v1=4 m10−15 m10[4pt]

⇒v1=2 m5−3 m2[4pt]

⇒v1=
