Answer:
r = 3 m
Explanation:
Given that,
Charge, [tex]q=1\ mu C[/tex]
Electric field at a point, [tex]E=1000\ N/C[/tex]
We need to find the distance away from it. We know that electric field at point r is given by :
[tex]E=\dfrac{kq}{r^2}\\\\r=\sqrt{\dfrac{kq}{E}} \\\\r=\sqrt{\dfrac{9\times 10^9\times 10^{-6}}{1000}} \\\\r=3\ m[/tex]
So, the required distance is 3 m.
