A uniform magnetic field of induction `B` is confined to a cyclindrical region of radius `R`. The magnetic field is increasing at a constant rate of `dB//dt` (tesla`//` second). A charge `e` of mass `m`, placed at the point `P` on the periphery of the fixed experiences an acceleration :

A uniform magentic field of induction B is confined in a cyclinderical region of radius R . If the field is incresing at a constant rate of (dB)/(dt)= alpha T//s , then the intensity of the electric field induced at point P , distant r from the axis as shown in the figure is proportional to :

A uniform magnetic field B exists in a cylindrical region, shown dotted in. The magnetic field increases at a constant rate (dB)/(dt) Consider a circle of radius r coaxial with the cylindrical region. (a) find the magnitude of the electric field E at a point on the circumference of the circle. (b) Consider a point P on the side of hte square circumscribing the circle. Show that the component of the induced electric field at P along ba is the same as the magnitude found in part(a).
