A highly conducting ring of radius $R$ is perpendicular to and concentric with the axis of a long solenoid as shown in fig. The ring has a narrow gap of width $d$ in its circumference. The solenoid has cross sectional area $A$ and a uniform internal field of magnitude $B_0.$ Now beginning at $t=0,$ the solenoid current is steadily increased to so that the field magnitude at any time $t$ is given by $B(t)=B_0+\alpha t$ where $\alpha>0.$ Assuming that no charge can flow across the gap, the end of ring which has excess of positive charge and the magnitude of induced $\text{e.m.f.}$ in the ring are respectively
