A neutron, a proton, and an electron are placed in a uniform electric field.
Correct answer: D. Magnitude of acceleration will be different
- A. The forces acting on them will be equal
- B. Their accelerations may be equal
- C. They may experience different motion in the field
- D. Magnitude of acceleration will be different
Explanation
The neutron (no charge) feels no force. The proton and electron feel forces of equal magnitude but opposite direction. Since their masses are very different, their accelerations (a = F/m) will also be different.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
