Conclusions
The main aim of this experiment is to find out whether or not the strength of the attraction between the charges affects the degree of ‘bend’ of the stream of water. The main hypothesis is that the strength of attraction does indeed affect the degree of ‘bend’ of the stream of water.
From the distance sub-experiment conducted, the results prove that closer the smaller the distance between the stream of water and the balloon, the stronger the attraction between the negative charges on the balloon and the positive charges in the stream of water.
From the charges sub-experiment conducted, the results prove that the higher the amount of charges on the balloon, the stronger the attraction between the negative charges on the balloon and the positive charges in the stream of water.
With the two sets of results and data at hand, it can be safely concluded that the main hypothesis is correct.
