An electric charge of 1 microcoulomb is affected by an electric field of intensity 1000 newtons per coulomb at a point, then this point is a meter away from it by a distance

Sagot :

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.
