Pls give the solution of this sum.
Three particles, each having a charge of 10μC are placed at the vertices of an equilateral triangle of side 10cm.Find the work done by a person in pulling them apart to infinite separation?

Arpan
try like this
first try to bring one charge from infinity to this point.
Then add another charge at a distance of 10 cm from the first point.
Then add another charge so this time there will be work done against two charges.
Does this help?
the potenial of the system is = 3*(9*109*10*10-6)/0.1
we know that potential*the toatal charge(that is 30μC)gives the amount of energy reqiured to remove them
