The figure shows a right angled isosceles triangle wire frame. The wire frame starts entering into the region of uniform magnetic field with constant velocity `v` at `t=0`. If I is the instantaneous current through the frame, then choose the corrent graph between I `&` t.

Figure shows an isosceles triangle wire frame with apex angle equal to (pi)//2 . The frame starts entering into the region of uniform magnetic field B with constant velocity v at t =0. The longest side of the frame is perpendicular to the direction of velocity. If i is the intantaneous current through the frame then choose the alternative showing the correct variation of i with time.
