An electric field with initial magnitude 190 V/m directed into the page and increasing at a rate of 17.0 V/(m · s) is confined to the area of radius R = 14.0 cm in the figure below. If r = 46.0 cm, what are the magnitude and direction of the magnetic field at point A?
a) magnitude 3,215e-16 Incorrect: Your answer is incorrect. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. T
b) direction Correct: Your answer is correct.
as we know
B L = uo eo d(phi) /dt
B ( 2 pi r) = uo eo A dE/ dt
B ( 2 pi * 0.46) = 4* 3.14* 10^-7* 8.85* 10^-12* 3.14 * 0.14^2* 17
B = 4* 10^-18 T

Comment in case any doubt, will reply for sure. Goodluck
