Okay, haven't done physics in years, let's see if I remember this.
So Coulomb's Law states that
so if we double the charge on 
and double the distance to 
we plug these into the equation to find
<span>
</span>
So we see the new force is exactly 1/2 of the old force so your answer should be
if I can remember my physics correctly.

Note: I'm not sure what do you mean by "weight 0.05 kg/L". I assume it means the mass per unit of length, so it should be "0.05 kg/m".
Solution:
The fundamental frequency in a standing wave is given by
where L is the length of the string, T the tension and m its mass. If we plug the data of the problem into the equation, we find
The wavelength of the standing wave is instead twice the length of the string:
So the speed of the wave is
And the time the pulse takes to reach the shop is the distance covered divided by the speed:
