SUMMARY
The discussion centers on calculating charge (Q) using the formula Q = W/V, where W is work and V is potential difference. The potential difference is given as 140mV, and the work required is 280μJ. The correct approach involves converting all units to joules and coulombs before performing the calculation, as dividing millijoules by millivolts yields coulombs, not millicoulombs. The user is advised to simplify the process by ensuring consistent units throughout the calculation.
