Answer:
r₂/r₁ = 1.82
Explanation:
The electric field due to a point charge, has the following expression:
For a distance r₁, the magnitude of the electric field is 395 N/C, so we can solve for r₁², as follows:
r₁² = (1)
For a distance r2, the magnitude of the electric field is 119 N/C, so we can solve for r₂², as follows:
r₂² =
We can find the quotient r₂/r₁, from (1) and (2):
r₂/r₁ = = 1.82
