Final answer:
To find the electric field (E) at a point P(1, 2, 3) due to a uniform line charge along the line y = -2, z = 5.
Step-by-step explanation:
To find the electric field (E) at a point P(1, 2, 3) due to a uniform line charge, you can use the principle of superposition. In this case, the line charge is defined by y = -2 and z = 5.
First, calculate the electric field due to the y-component of the line charge. The electric field E due to a linear charge density (λ) can be calculated using the equation E = k * λ / r.
Next, calculate the electric field due to the z-component of the line charge using the same equation. Finally, add the two electric field vectors to get the total electric field at point P.
