Negatively charged particles were accelerated from rest between a pair of parallel metal plates. The potential difference between the plates was varied, and the final velocity of the particles was measured for each variation.
The data in the table show the potential difference between the plates and the square of the corresponding final velocity of the particles.
- Plot the data on the grid provided and draw a line of best fit.
