Two cells of emfs 1.5V and 2.0V and internal resistances 2Ω and 1Ω respectively have their negative terminals joined by a wire of 6Ω and positive
terminals by a wire of 7Ω resistance. A third resistance wire of 8Ω connects middle points of those wires. Find the potential difference at the end of the third wire.
a) 2.25V b) 1.36V c) 1.26V d) 2.72V
