Calculation of cell potentail

Three point charges 2muC, 3muC and 5muC are placed at the corners of an equilateral triangle of side 200 cm. Calculate the potentail energy of the system.

There is an infinitely long straight thread carrying a charge with linear density lambda = 0.40 muC//m . Calculate the potentail difference between points I and 2 is removed eta = 2.0 times farhter from the thread than point 1.

The value of solute potentail is

Two cells, having the same emf, are connected in series through an external resistance R . Cells have internal resistance r_(1) and r_(2) (r_(1) gt r_(2)) respectively. When the circuit is closed, the potentail difference across the first cell is zero the value of R is
