Final answer:
The magnitude of the point charge that would create an electric field of 1 N/C at a distance of 1.0 m is 9 x 10^9 C.
Step-by-step explanation:
The magnitude of the electric field E created by a point charge is given by the formula E = k * (Q / r^2), where k is the electrostatic constant (9 x 10^9 N m^2/C^2), Q is the charge of the point charge, and r is the distance from the charge. In this case, we need to find the magnitude of the point charge that would create an electric field of 1 N/C at a distance of 1.0 m. Plugging in the given values, we have 1 = (9 x 10^9) * (Q / 1^2). Solving for Q, we get Q = 9 x 10^9 C.
