Final answer:
The strength of the electric field E due to a point charge can be calculated using the equation E = kQ/r^2, where E is the electric field strength, k is the Coulomb's constant, Q is the charge, and r is the distance from the charge. To calculate the strength of the electric field due to a point charge of 7.00 nC at a distance of 8.00 m, plug in the values into the equation E = (k * Q) / r^2. The direction of the electric field is radially outward from the point charge.
Step-by-step explanation:
The strength of the electric field E due to a point charge can be calculated using the equation E = kQ/r^2, where E is the electric field strength, k is the Coulomb's constant, Q is the charge, and r is the distance from the charge.
To calculate the strength of the electric field due to a point charge of 7.00 nC at a distance of 8.00 m, we need to substitute the values into the equation:
E = (k * Q) / r^2
Plugging in the values, we get:
E = (8.99 x 10^9 Nm^2/C^2 * 7.00 x 10^-9 C) / (8.00 m)^2
Simplifying the equation gives:
E = 7.00 x 10^9 N/C
The direction of the electric field is radially outward from the point charge.
