figure shows an electrical circuit which has a rectangular region of uniform and constant magnetic field B.a long metallic sheet of width is being moved with velocity v.reading of galvanometer G will be​

Answer 1

Explanation:

Environmental science is an interdisciplinary academic field that integrates physical, biological and information sciences to the study of the environment, and the solution of environmental problems. Environmental science emerged from the fields of natural history and medicine during the Enlightenment.

Answer 2

The reading of galvanometer G is Rr

Explanation:

• The induced emf is predicted to be regular simplest withinside the case of the square loop.

• In the case of round loop, the rate of change of area of the loop throughout its passage out of the sphere region is not regular, therefore induced emf will range accordingly. so the emf induced alongside length' e

                       e = CV x B J.

             =) VBI Current reading of galvanometer

                i = e =) e-emf incluced

                        r = resistance :

                     2= VB i R ohm

Answer is R r
