1.	Three charges `+q, 2 q and -4q` are placed on the three vertices of an equale-laterail triangle of each side`0*1m`. Calculate electrostatic potential energy of the system, take `q = 10^(-7) C`
Answer» Potential Energy of system of charges = `(1)/(4pi in_(0) r) [q(2q) + 2q + (-4q) + (-4q)q]` `= (10q^(2))/(4pi in_(0) r) = (9xx10^(9)xx10(10^(-7))^(2))/(0*1) = 9xx10^(-3) J`.
