The total charge Q = 0.46 nC
Explanation:
It is given in the question that both charges are equal so
Q1 = Q2 = Q
Force = F = 6 × 10^(-8) N
Distance between charges = r = 18 cm
According to coulomb’s Law
F = K Q1 Q2/r^2
And
Q = (F* r^2 / K )^(1/2)
By putting values in above equation, we get
Q = 0.46 nC
