Question

An object is placed in front of a spherical mirror. The image is real, inverted, and smaller than the object. What type of mirror is this and where is the object placed? (a) convex; anywhere (b) concave: between the lens and the focal point (c) concave: between one and two focal lengths from the mirror (d) concave: more than two focal lengths from the mirror (e) this situation is impossible A bundle of charge, Delta q, leaves a battery and moves across resistor. After crossing the resistor, the electrostatic potential energy of the bundle of charge is (a) less than it was before crossing the resistor. (b) more than it was before crossing the resistor. (c) equal to what it was before crossing the resistor.

Explanation / Answer

option (d) is correct.

a) convex mirror always produce virtual errect and diminished image

b) option b is not correct as it is mentioned lens instead of mirror. if object is placed between mirror and focal point then virtual errect magnified image is formed.

c) if object is placed between one and two focal lenght from the mirror then real, inverted and magnified image is formed.

d) if object is palced more than two focal lenght from the mirror, then real, inverted and diminished image is formed.

so in this question concave mirror is used and object is placed at more than two focal lenght from the mirror
