Question

An electric field measured near a point charge of 3.00 × 10^-6 C has a strength of 1.50 × 10^5 N/C. How far is the point from the source charge?

A.0.095 m
B.0.30 m
C.0.36 m
D.0.42

Answer 1

Actually can you help me on my question Michele_Laino

Answer 2

here w have to apply this formula:
\[\large E = K\frac{Q}{{{d^2}}}\]
so we have:
\[\large d = \sqrt {\frac{{KQ}}{E}} \]
where K=9*10^9, E is the electric field, and Q is the charge
