A charged parallel-plate capacitor has an electric field E0 between its plates. Ignore the force of gravity. Note the approximations:
mproton ≈2000 melectron,
melectron ≈ 9 x 10–31 kg,
qproton = 1.6 x 10–19 C.
The bare nuclei of 1H and of 4He are between the plates, and both are at rest. How does the magnitude of the acceleration of the hydrogen nucleus aH compare with the magnitude of the acceleration of the helium nucleus aHe?
