Question

How should I set up equations?

Several species of bacteria, including Geobacter metallireducens, have been shown to "eat" electrons, bypassing the usual process of metabolizing sugar to obtain energy. During this
process, the bacteria, which already have negatively charged cell membranes, acquire an even larger net negative charge, typically between 10.0e and 85.0e in magnitude. Individual
Geobacter are typically 4.00 pm in diameter.
What are the magnitude and the direction of the electric field of a bacterium with a net negative charge of magnitude 45.0e at a distance of 1.60 mm from the microbe?
(a) the magnitude (in N/C)
|N/C
(b) the direction
O radially outward
O radially inward
What are the magnitude and the direction of the electric force on a second bacterium of net negative charge 50.0e a distance of 1.60 mm from the first bacterium?
(c) the magnitude (in N)
(d) the direction
O away from the first bacterium
O towards the first bacterium
