In a single measurement student applied electron gun accelerating voltage of 240 V and measured electron orbital diameter of 8 cm. The applied magnetic induction was the same as in Problem 1. What specific charge of the electron follows from the above measurement

i believe it is b. what was the cause of the big bang

hope this !

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.

e/c, where e is its total energy
