Saccharomyces cerevisiae is a single-celled yeast that is often used as a model for eukaryotic cells, as it contains all of the important organelles of these cells. The genome of Saccharomyces cerevisiae, commonly known as brewer's yeast, has been completely mapped, making it suitable for genetic engineering experiments. The amount of electric charge on the cell walls plays a significant role in the interaction of these cells with their environment. To determine the electric charge on yeast cells, which is a function of their size, the cells are often placed in electric fields and their motion in these fields is measured. In one such experiment, Saccharomyces cells of mass 3.00 x 10-9 g placed at rest in a uniform electric field of magnitude 10.0 N/C were measured to be traveling with a speed of 3.10 x 102 µm/s after traversing a distance of 20.0 um along the direction of the electric field. What was the magnitude and sign of the charge on this batch of yeast cells? (a) magnitude (in C) с (b) sign of the charge positive negative neutral
