Understanding Potential Difference and Work Done by Electric Fields

What is the initial potential at the point from which the proton is moved?

• 0 Volts

• 220 Volts

• -65 Volts

• 155 Volts

Which equation relates the change in potential energy to the charge and potential difference?

• F = ma

• V = IR

• E = mc^2

• ΔU = Q * ΔV

What happens to a positive charge when it is moved across an electric field to a positive plate?

• It becomes negatively charged.

• It loses potential energy.

• It gains potential energy.

• It remains neutral.

What is the relationship between potential energy, work, and kinetic energy?

• They are all equal to the amount of charge and potential difference.

• They are unrelated.

• They are only related in gravitational fields.

• They are inversely proportional.

What happens to the kinetic energy of the proton as it moves across the field?

• It becomes zero.

• It increases.

• It remains constant.

• It decreases.

What is the significance of the conservation of energy in this context?

• It indicates that energy is irrelevant.

• It highlights that energy is transformed but conserved.

• It demonstrates that energy is created.

• It shows that energy is lost.
