Question

Qi Magnification produced by a plane mirror is +1. What does this mean?
Q2 A convex lens of focal length 20 cm can produce a magnified virtual as well as
real image. Is this a correct statement? If yes, where shall the object be placed in
each case for obtaining these images?
Under what condition in an arrangement of two plane mirrors, incident ray and 02
reflected ray will always be parallel to each other, whatever may be the angle of
incidence. Show the same with the help of a diagram.
A wire of resistance 200 is bent to form a closed square. What is the resistance
across a diagonal of the square?
05 | How is the direction of electric current related to the direction of flow of electrons TOT
in a wire?
06 Calculate the current in a circuit if 500 coulomb charge passes through it in 10 01
minutes.
​

Answer 1

1.This means that the mirror is concave if the object is between Pole and Focus and convex mirror for all the object positions

2.No, it cant produce real image..convex mirror only produces virtual and erect images

3.
