En un átomo de hidrógeno un electron gira al rededor de un proton en una órbita de radio igual a 5.3×10 a la-11m ¿Con que fuerza se atraen si la carga de electrón es de -1.6×10 a la -19 (y la del portón es de +1.6×10 a la -19 C)?

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
