In the circuit diagram shown, the wire PQ has the resistance of 5Ω5Ω$ and the driver cell has an emf of 2.00 V. What is the value of the resistance R if a balance point is obtained at 0.60 m along PQ when measuring an emf of 6.00mV?
495Ω495Ω
95Ω95Ω
995Ω995Ω
195Ω195Ω
can anyone answer this question?
