The direction of the vector with respect to the x-axis
is the angle whose tangent is (4/5) .
Arctan(4/5) = 38.7° counterclockwise from the x-axis.
A force that results from charged particles is called<u> </u><u>"electrostatic force".</u>
Hope this helps!

The answer to life is how ever you make it...... you can do anything with life that you would like.................. But make your choices worth it......
Answer:
Now e is due to the ring at a
So
We say
1/4πEo(ea/ a²+a²)^3/2
= 1/4πEo ea/2√2a³
So here E is faced towards the ring
Next is E due to a point at the centre
So
E² = 1/4πEo ( e/a²)
Finally we get the total
Et= E²-E
= e/4πEo(2√2-1/2√2)
So the direction here is away from the ring
