The answer is C! I knew this way before taking the test
Electric potential energy, or Electrostatic potential energy, is a potential energy (measured in joules) that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system.
The period of motion is given as π/2(√md³/KeqQ)
What is Coulombs law?
Coulomb's law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.
The period of motion from the instance given π/2(√md³/KeqQ).
w²= (2π/T)²
T=2π/w
where w is gotten as 16KeqQ/md³
T= π/2(√md³/KeqQ).
m is the mass of the body with charge-Q
In conclusion, the Coulomb's law equation provides an accurate description of the force between two objects whenever the objects act as point charges.
