Explanation:
By introducing a particle of one positive coulomb between the electric plates, the particle experience a force against the electrostatic forces, proving that it is in an electric field
The force experienced by this particle is known as Electric Field Intensity denoted by E and it is given by
where, k is constant =
q is the charge magnitude on the particle
r is the separation of the particles

= 20.75 Watts or 20.75 J/s
Explanation:
Power is given by the formula;
Power = work done/time
But; work done = Force ×distance
Therefore;
Work done= 6.4 N × 10.7 m
= 68.48 Nm
Thus;
Power = 68.48 Nm / 3.3 s
= 20.75 Watts or 20.75 J/s
