Answer:
16916.4 V
Explanation:
Electric potential: This is the work done in bringing a unit positive charge from infinity to that point in against the action of the field. The S.I unit of Electric potential is V.
mathematically, Electric potential can be expressed as
P = E×d ....................................... Equation 1.
Where P = Electric potential, E = Electric Field, d = distance/height of the level at the top of the Washington Monument.
Given: E = 100 V/m, d = 555 ft = 555×0.3048 m = 169.164 m.
Substitute into equation 1
P = 100×169.164
P = 16916.4 V.
Thus the potential difference = 16916.4 V.
Many fundamental laws of physics and chemistry can be formulated when doing this.
