A"free" electron and a "free" proton are placed in an identical electric field. which of the following statements are true?
(selectall that apply.)
a. each particle is acted upon by the sameelectric force and has the same acceleration.
b. the magnitude of the acceleration of theelectron is greater than that of the proton.
c. the electric force on the proton isgreater in magnitude than the electric force on the electron, butin the opposite direction.
d. both particles have the same acceleration.
e. the electric force on the proton is equalin magnitude to the electric force on the electron, but in the opposite direction.

The statements which are true of a "free" electron and a "free" proton are placed in an identical electric field are: Choice b and Choice e.

According to the question:

In essence, the magnitude of the Coulumb's force of attraction or repulsion is the same for the free electron and free proton.

However, the direction of the forces are opposite as the protons and electron have opposing signs.

Additionally, since the mass of an electron is relatively infinitesimal compared to a proton, The acceleration of the electron is greater than that of the proton.

b and e

Explanation:

When electron and proton are placed in the same Electric field then the force experienced by electron and proton is the same as the charge possessed by them is the same . The direction of force is different on them but the magnitude is the same.

The electric field force is the product of charge and strength of the electric field.

We know the mass of an electron is less than the mass of proton that is why the acceleration of electron is more as compared to proton for the same Electric force.

thus option b and e are correct.
