A proton is released from rest in a unifrom electric field. Does the proton's electric potential energy increase or decrease? Does the proton move towards a location with a higher or a lower electric potential.

Text Solution

Verified by Experts

The potential enerfy of the proton decreases (as it gains kinetic energy due to its motion in the electric field) Further the proton (being positive) moves from higher to lower electric potential.

  • A positively charged particle is released from rest in an uniform electric field. The electric potential energy of the charge

    A
    remains a constant because the electric field is uniform.
    B
    increases because the charge moves along the electric field.
    C
    decreases because the charge moves along the electric field.
    D
    decreases because the charge moves opposite to the electric field.
