1.	An isulating pipe of cross-section area `A` contains an electrolyte which has two types of ions: their charges being-e and `+ 2e`. A potential difference applied between eht ends of the pipe result in the drifting of the two types of ions, having drift speed `= v (- ve ion)` and `v//4(+ ve ion)`. Both ions have the same number per unit volume `= n`. The current flowing through the pipe isA. `(1)/(2) n e v A`B. `(1)/(5) n e v A`C. `(5)/(2) n e v A`D. `(3)/(2) n e v A`
Answer» Correct Answer - D (d) `i= n e v_(d) A, I = (2 n e v A)/(4) - (- n e vA) = (3)/(2) n e v A`
