A charged particle (q = –8.0 mC), which moves in a region where the only force acting on the particle is an electric force, is released from rest at point A. At point B the kinetic energy of the particle is equal to 4.8 J. What is the electric potential difference VB – VA? Group of answer choices –0.80 kV +0.80 kV –0.48 kV –0.60 kV +0.60 kV

The electric potential difference between two given points is

Explanation:

Here we know that work done by electrostatic force = change in its kinetic energy

   work done=

since Δv = =

Δv == =

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
