Un electrón tiene una carga de -1.6x10-19C y un protón tiene una carga de 1.6x10-19C. En un átomo de hidrógeno, la distancia entre ellos es de 5.3x10-11m. Determina la fuerza electrostática entre ellos.

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
