An 8.50 kg point mass and a 14.5 kg point mass are held in place 50.0 cm apart. A particle of mass (m) is released from a point between the two masses 12.0 cm from the 8.50 kg mass along the line connecting the two fixed masses. Find the magnitude of the acceleration of the particle.

Explanation:

From the question we are told that:

First Mass

2nd Mass

Distance

Generally the Newtons equation for Gravitational force is mathematically given by

Therefore

Initial force on m

Final force on m

Acceleration of m

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.
