In the presence of an electrostatic field, you find that you must do positive work on a proton to move it from point A to point B without changing its kinetic energy.

Considering just the proton as your system, have you increased, decreased, or left unchanged its electric potential energy?

a. increased
b. decreased
c. left unchanged

Respuesta :

Answer:

The potential energy decreases

Explanation:

  • When a proton moves in the direction of the electric field, the force on the proton (f=qE) will be in the direction of the field.
  • The proton will accelerate and the KINETIC energy will increase.
  • The potential energy decreases.
