In which case does the ptential energy decrease?

(a) What is the electric potential energy of two electrons separated by 3.00 nm? (b) If the separation increases, does the potential energy increase or decrease ?

Three charged particles ( their sign are shown ) move along the path in a uniform electric field as shown . In each of three cases, wheather the potential energy increases or decreases.

In which of the following cases, the potential energy of the given particles decreases (under the given condition)

In which of the following cases, the potential energy of the given particles decreases (under the given condition)

In which of the following cases the, potential energy is defined?

As an electron makes a transition from an excited state to the ground state of a hydrogen like atom/ion (a) kinetic energy, potential energy and total energy decrease (b) kinetic energy decreases, potential energy increases but total energy remains same (c ) kinetic energy and total energy decrease but potential energy increases (d) its kinetic energy increases but potential energy and total energy decrease
