Electrostatics and work question

Click For Summary
SUMMARY

The discussion focuses on calculating the work required to transfer two charges, 40nC and -50nC, from infinity to specific coordinates (0,0,1) and (2,0,0) respectively. The formula used is W=(1/(4∏ε))*((40n*-50n)/(mag((2,0,0)-(0,0,1))), resulting in a work value of -8.05 μN. The correctness of the formula and the calculations are confirmed by participants, indicating that the approach is valid if the math is executed accurately.
