We know the relation between current (I), charge (Q), and time (t): \[ I = \frac{Q}{t} \] Given: Q = 6 C, t = 2 minutes = 120 seconds Substitute into the formula: \[ I = \frac{6}{120} = 0.05 \text{ A} \]
The correct option is (C): \(0.05A\)
An infinitely long straight wire carrying current $I$ is bent in a planar shape as shown in the diagram. The radius of the circular part is $r$. The magnetic field at the centre $O$ of the circular loop is :
