The electron cloud model is a modern theory about the structure of atoms that explains many of the atom’s behaviors. according to the model, scientists imagine an atom to have a large nucleus of matter in the center surrounded by tiny particles called electrons. these electrons fly so fast and unpredictably around the nucleus that just one electron can appear to be a cloud. however, individual electrons are far too small for a human to see or touch. what is a limitation of the electron cloud model theory that a law about electrons would not have?

Couldn't explain that electrons behaves as both particles and waves.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
