Answer:
The electric potential at a point in space is defined as the amount of work done per unit charge to bring a test charge from infinity to that point 1. The electric potential at a height of 1 meter above the ground can be calculated using the following formula:
V = k * Q / r
where V is the electric potential, k is Coulomb’s constant (8.99 x 10^9 N m^2 C^-2), Q is the charge density (-1.00 nC/m²), and r is the distance from the point to the center of the Earth (6,371,000 meters) 12. Substituting these values into the formula, we get:
V = (8.99 x 10^9 N m^2 C^-2) * (-1.00 x 10^-9 C/m²) / (6,371,000 m + 1 m) V = -1.40 x 10^-13 V
Therefore, the electric potential at a height of 1 meter above the ground on a fine day out in the open country is approximately -1.40 x 10^-13 V.
