Calcular la masa de un cuerpo que adquiere la aceleración de 8,8m/s2, cuando sobre el actúa una fuerza de 8000000 dinas. Explicación paso a paso

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
