Answer 1

Answer #1

here,

Q1 = 10 q , Q2 = 5q

Q3 = - 12 q

the electric potential energy stored , E = k *q1 * q2 /(3r)^2 + k * q2 * q3 /(5r)^2 + k * q3 * q1 /(4r^2)

E = - k * 10q * 12q/(3r)^2 - k * 12 q * 5 q /(5r)^2 + k * 10q * 5q /(4r)^2

E = - 12.6 k * q^2 /r^2

the electric potential energy stored is - 12.6 k * q^2 /r^2
