We know that,
KE = (1/2)mv^2
F = mv^2 /r
Solving both, F = 2KE/r
F = 2*50/3.5 = 28.57 N
The line breaks when the tension is 28.57 N
F' = 2*52/3.5 = 29.71 N
Now, Resultant force F'
F' = F + Fa
Where, Fa is attraction force. So it is negative
Fa = 29.71 - 28.57 = 1.14 N
By using Columbs law,
F = Kq1*q2/d^2
- 1.14 = 9*10^9*(+q)*(-q)/(3.5)^2
q^2 = 1.14*(3.5)^2 /(9*10^9)
q = 4*10^-5 C
