# If the protons in the nucleus of an atom repel each other due to electromagnetic forces, why doesn't the nucleus just fly apart?

Because the electromagnetic attractive force due to the heavier neutrons is stronger than the electromagnetic repulsive force of the protons.

Because the gravitational attraction between the protons is stronger than the electromagnetic repulsion between them.

Because the strong force holding the protons together is stronger than the electromagnetic force trying to push them apart.

Because the pressure that the electron cloud exerts on the nucleus holds them in place.

You can eliminate some of the options

< Because the electromagnetic attractive force due to the heavier neutrons is stronger than the electromagnetic repulsive force of the protons. >.  Neutrons have no charge so there would be no electromagnetic force.

< Because the gravitational attraction between the protons is stronger than the electromagnetic repulsion between them. > Gravity is by FAR the weakest of the 4 forces so that is clearly wrong.

< Because the strong force holding the protons together is stronger than the electromagnetic force trying to push them apart. > That sounds like it's possible.  Let's see the last one.

< Because the pressure that the electron cloud exerts on the nucleus holds them in place. >. No such thing so it can be eliminated.  by the process of elimination, you have only choice 3 left.

what a badly formulated question. the neutrons hold the protons together, but not by electromagnetic or gravitational means, and pressure by electroncloud is pure nonsense

the strong nuclear force is strongest of all the fundamental forces and overcomes other forces such as electro=magnetic
