The change of the radius of the circle with respect to time is expressedby r= ra(1+3t). The circle begins to expand at the moment t = 0. (Assume that the resistance R does not change inthis process).For t=1s, find the magnitude and direction of the current formed in the circle.(R= 5 Ohm, 3 = 3TR, n =1cm )
