Two tangent galvanometers A and B have coils of radii 8‌cm and 16‌cm respectively and resistance 8Ω each. They are connected in parallel with a cell of emf 4V and negligible internal resistance. The deflections produced in the T.G's A and B are 30∘ and 60∘ respectively. If A has 2 turns, then B must have
