Charge is distributed within a solid sphere of radius r0 in such a way that the charge density is a function of the radial position within the sphere of the form: rhoe(r)=rho0rr0. part a if the total charge within the sphere is q (and positive), what is the magnitude of the electric field everywhere within the sphere in terms of q, r0, and the radial position r?

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
