Where is the 0.707 coming from? And I plugged k= 8.99 x 10^9, q= 2.65 x 10^-6, and s= 0.408 into the net force toward the center equation to get 0.347N. So this is the magnitude that all of the charges would have, correct?

for x = 8 do u use between x =6 and x=8 and between x=8 and x=10?

calculus. please helppp!!
so then for x = 8, u do the exact same steps by dividing the numbers by 2?

calculus. please helppp!!
yeah for 2 but when I tried that for x = 8, I have a huge gap between the two numbers for 8. I got between x=0 and x =8, it is -88. then dividing that by 8, i got -11. then when i did between x= 8 and x =10, i got -55. then dividing that by 8, i got -1.875 and now I'm stuck

I'm getting confused on x= 8 would you do between x=0 and x= 8, the change is -88 and then divide that by 8 = -11 between x= 8 and x= 10, y changes -15 and then divide that by 8 to get -1.875 but then what?

oh ok. but wut about f^'(2). how do i find that from the table?
