A neutron, a proton, and an electron are placed in a uniform electric field. The:
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. Magnitude of acceleration may be equal
- D. Magnitude of acceleration will be different
Explanation
Force on neutron = 0 (as charge = 0) Force on proton = qE Force on electron = - qE Masses of proton and electron are different. Hence, their accelerations will be different. ∴ Hence, (D) is correct.

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.
