Over a region of radius R, there is a spatially uniform magnetic field B. (See below.) At t = 0, B = 1.3 T, after which it decreases at a constant rate to zero in 28 s. E(r) = P (d) dt X dB R² dt 2r x X (a) What is the electric field as a function of distance from the center of the given region where r s R and r2 R during that 28 s interval? (Enter the magnitude. Use any variable or symbol stated above along with the following magnitude of the change in the magnetic field with respect to time. Do not substitute numerical values; use variables only.) rsR R r2R X x x X (b) Assume that R = 11.0 cm.
