Aprotein molecule in an electrophoresis gel has a negative charge. the exact charge depends on the ph of the solution, but 30 excess electrons is typical. what is the magnitude of the electric force on a protein with this charge in a 1600n/c electric field? write in two significant numbers, and also in newton

The charge on a charged sphere is; 1. concentrated at its center 2. distributed uniformly throughout its volume 3. clustered on its center 4. distributed uniformly over its surface
