Answer:
4.6
Explanation:
To calculate the magnitude of the electric field, you can use the formula:
E = k * |q| / r^2
where:
E is the magnitude of the electric field
k is the Coulomb constant, approximately 8.99 x 10^9 N*m^2/C^2
|q| is the absolute value of the charge, 3.2 nC (3.2 x 10^-9 C)
r is the distance from the charge, 2.5 m
Plugging in the values, we get:
E = (8.99 x 10^9 N*m^2/C^2) * (3.2 x 10^-9 C) / (2.5 m)^2
E = (2.8768 x 10^1) / (6.25)
E = 4.6 x 10^0
Therefore, the magnitude of the electric field for a charge of 3.2 nC at a distance of 2.5 m is approximately 4.6 x 10^0 N/C.
