Question: A wire forms a closed circular loop, with radius R = 4 . 8 m and resistance 4 . 9 ohms. The circle is centered

A wire forms a closed circular loop, with radius R=4.8 m and resistance 4.9 ohms. The circle is centered on a long straight wire; at time t=0, the current in the long straight wire is 7.5 A rightward. Thereafter, the current changes according to i=7.5 A
