The total work done in assembling the point charges 'q1', 'q2' and 'q3' is equal to _________________. (r12, r23 and r31 are the distances between these
charges)
1
1/(4πεo) x √(q1q2/r12 + q2q3/r23 + q3q1/r31)
2
1/(4πεo) x (q1q2/r12 + q2q3/r23 + q3q1/r31)
3
1/(4πεo) x (q1q2/r12 + q2q3/r23 + q3q1/r31)-1
4
1/(4πεo) x [√(q1q2/r12 + q2q3/r23 + q3q1/r31)]-1
