Question

Here is a cube made from twelve wire each of length l. An ant goes from A to G through path A-B-C-G.
Calculate the displacement.

Answer 1

Answer:

Since branches parallel to z axis are equipotential as no emf is induced in them, we can replace cd with a battery of V=vBL=2.2.5=10V and a resistor of 10Ω and cg, gh and dh with wires of resistance 10Ω each since in this case gh will be out of magnetic field. Hence Voltage across dh will be 5V

Answer 2

Answer:

this correct answer is √3l
