Question

- What will be the field strength from a 1.25* 10^-3 when measured 0.4m from the charge?

Answer 1

Step-by-step explanation:

I'm assuming your charge is in Coulombs so I will proceed that way. The formula for this electric field problem is

`E=(kQ)/(r^2)` where k = 9.0 × 10⁹. Filling in:

`E=((9.0*10^9)(1.25*10^(-3)))/(.4^2)` gives us an electric field value of

7.0 × 10⁷ N/C
