The force experienced by a proton of charge e placed in an electric field E is- Correct Answer eE

CONCEPT:

  • Electric field force (F): When a charged particle is placed in an electric field, a force will act on it, which is known as electric field force.
    • Due to the electric field, the force always acts in the direction of the electric field on a positive charge and acts in the opposite direction of the electric field on a negative charge.

F = qE

where F is the force due to the electric field, q is the charge, and E is the electric field.

EXPLANATION:

Given that proton charge q = e and electric field E (downward)

So force F = qE

F = eE

  • Force will be downward as Force is always in the direction of the electric field on a positive charge.

So the correct answer is option 1.
