A ring has a radius of 71 cm. It has 10 more protons than electrons. This net charge is distributed uniformly over it. What is the electric field at point P, which is on the axis of the ring, and 83 cm from its center?

step-by-step explanation:

what's that

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

they disappear if your absent from to long. i found out that the hard way.

brainliest lol i just need one more brainliest.
