Athin, horizontal square copper plate has a length of 6.35cm and is charged with 2.56 × 108 electrons. if the electrons are uniformly distributed on the surface, calculate the value of the electric field (with the upward direction positive).
why is the strength of the electric field at the plate's centre of mass?

where are the vectors ?

  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
