Answer 1

Calculation of the Charge Creating the Electric Field

To determine the magnitude of the charge creating the electric field, we can use the formula for the electric field created by a point charge in vacuum:

E = k * (q / r^2)

Where: - E is the electric field strength - k is the electrostatic constant (approximately equal to 9 x 10^9 Nm^2/C^2) - q is the magnitude of the charge creating the field - r is the distance from the charge to the point where the field is measured

In this case, we are given the following information: - The electric field strength E is 36 V/m (volts per meter). - The distance r is 15 cm, which is equal to 0.15 m.

We can rearrange the formula to solve for the magnitude of the charge q:

q = E * r^2 / k

Substituting the given values:

q = (36 V/m) * (0.15 m)^2 / (9 x 10^9 Nm^2/C^2)

Now we can calculate the magnitude of the charge q.
