Question

What is the electric field at a distance of 2.5 m from a 550 μC charge?

A) 220 N/C
B) 440 N/C
C) 110 N/C
D) 880 N/C

Answer 1

The electric field at a distance of 2.5 m from a 550 µC charge is 19872 N/C.

Step-by-step explanation:

To calculate the electric field at a distance from a point charge, we can use the equation E = kQ/r², where E is the electric field, k is the electrostatic constant (9 x 10^9 Nm²/C²), Q is the charge, and r is the distance from the charge. In this case, the charge is 550 µC (550 x 10^-6 C) and the distance is 2.5 m. Plugging in the values, we get:

E = (9 x 10^9 Nm²/C²) * (550 x 10^-6 C) / (2.5 m)²

E = 19872 N/C

Therefore, the electric field at a distance of 2.5 m from a 550 µC charge is 19872 N/C.
