Explanation:
Even if the athelete runs four laps of a 400 m track, its displacement will be 0 because the displacement is the shortest distance from its to final position. And, here the final and initial position is same since he comes to its initial position after covering certain distance. So, displacement is 0.
The electrostatic force acting on a charge q is given by
where E is the electric field's intensity.
In our problem, the particle is an electron, so its charge is
. We know the intensity of the force, so we can find the magnitude of the electric field at the point where the electron is located:
where the negative sign means that the force and the electric field have opposite direction, because the charge is negative.
