An electric field is restricted to a circular area of diameter d = 10.1 cm as shown in the figure. Éout Ⓡ At the instant shown, the field direction is out of the page, its magnitude is 300 V/m, and its magnitude is increasing at a rate of 18.0 V/(m. s). (a) What is the direction of the magnetic field at the point P, r = 14.1 cm from the center of the circle? Ⓒ upwards O downwards (b) What is the magnitude of the magnetic field (in T) at the point P, r = 14.1 cm from the center of the circle? 1.81E-12 X Apply the extended form of Ampere's law. Note that I = 0 in this case. What is the electric flux? What is the rate of change of the electric flux? T (c) What If? As before, at the moment shown in the figure, the electric field within the circle has a magnitude of 300 V/m and is increasing at a rate of 18.0 V/(ms). In addition, suppose that the radius of the circular area of the electric field increases at a rate of 1.00 cm/s. What would the magnitude of the magnetic field be at point P at this moment (in T)?
