## anonymous one year ago An electric field is measured at 3.00 × 10^5 N/C at a distance from a source point charge of 3.00 × 10^-6 C. How far is the point from the source charge? A. 0.09 m B. 0.30 m C. 0.36 m D. 0.60 m

the requested distance is given by the subsequent formula: $\large d = \sqrt {\frac{{KQ}}{E}} = \sqrt {\frac{{9 \times {{10}^9} \times 3 \times {{10}^{ - 6}}}}{{3 \times {{10}^5}}}}$

ok! so we get 0.3? so choice B is our solution?

3. Michele_Laino

yes! correct!
