q1 = 15 uC
q1 = 15 * 10^-6 C
q2 = -28 uC
q2 = -28 * 10^-6 C
q3 = + 24 uC
q3 = 24 * 10^-6 C
q4 = - 32 uC
q4 = -32 * 10^-6 C
a = 26 cm
a = 0.26 m
the electric potential energy of the entire system is ,Utotal = U12 + u13 + U14 + U23 + U24 + U34
Utotal = 9*10^9 * 10^-6 * 10^-6 *(15 * (-28)/.26 - 15 * 32/(sqrt(2) * 0.13) + 24 * 15 /(sqrt(2) * 0.26) - 24 * 28/0.26 + 32 * 28/(sqrt(2) * 0.13) - 32 * 24/(sqrt(2) * 0.13) )
Utotal = - 46.22 J
the electric potential energy of the entire system is - 46.22 J
