The figure shows a conducting loop consisting of half circle of area \[A=0.06\,{{m}^{2}}\] and three straight segments. The half circle lies in a uniform changing magnetic field \[B=4{{r}^{2}}+2t+5\] (SI unit), where t is the time in second. An ideal battery E=2V is connected as shown and the total resistance of the wire is \[2\Omega \]. The net current in the loop is at t=5 second is: |
