Homework Statement Two small spheres, each of mass 8.00 g , are suspended by light strings 15.0 cm in length (see figure). A uniform electric field is applied in the x direction. The spheres have charges equal to -6*10^-8 and 6*10^-8 Determine the electric field that enables the spheres to...

I don't really understand... my data is like below distance(m) 1 1.3 1.5 1.69 vel(m/s) 1.1675 1.325 1.4275 1.51 How can I prove what kind of function is it?? The graph looks like this...

Homework Statement Why is a parabola formed when a graph of distance(y axis) vs. velocity(x axis) is plotted against each other? (constant acceleration) Homework Equations s=ut+1/2at^2 (guessing?) v^2-u^2 = 2as (guessing?) The Attempt at a Solution I don't know if there is any...
