Answer:

E=\dfrac{KQx}{(x^2+a^2)^{\frac{3}{2}}}

Step-by-step explanation:

Given that

Radius of ring=a

Distance of point P from center=x

Total charge=Q

We know that electric field is given by

E=\dfrac{KQcos\theta }{r^3}

Here electric field in two direction will be cancel out and only in one direction electric field will exits.

 cos\theta =\dfrac{x}{r}

r^2=x^2+a^2

E=\dfrac{KQx}{(x^2+a^2)^{\frac{3}{2}}}
