Question

How can u prove that there is an electric field

Answer 1

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

$k \times \frac{q {}^{2} }{r}$

where, k is constant =

$9 \times {10}^{9}$

q is the charge magnitude on the particle

r is the separation of the particles
