Question

A uniform but time varying magnetic field exists in cylindrical region and directed into the paper. If field decreases with time and a positive charge is placed at any point inside the region, then it moves :-

(1)
along 1
(2)
along 2
(3)
along 3
(4)
along 4

Answer 1

Answer:

the varying moves a long with (3)along 3 with cylindrical

Answer 2

Answer:

The field is decreasing so in order to increase it the charge will move along 4 and so induced charge will increase thereby increasing the magnetic field
