Question
Can someone please show me a step-by step on how to solve this problem? I have tried a million different ways and keep getting an incorect answer. Please keep in the terms of the values expressed (keep radius "R" keep "P" keep "d" etc).
it shouldn't be as hard as i'm making it!
Thanks
Explanation / Answer
E = k Q x / (x^2 + R^2)^3/2 formula for E at distance x from ring of
radius R
E1 = k Q1 R / (2 R^2)^3/2 field for ring 1
E2 = 2 k Q2 R / (5 R^2)3/2 field for ring 2
E1 / E2 = 1/2 (Q1 / Q2) (5 / 2)^3/2 = 1/2 (Q1 / Q2) * 3.95
Q1 / Q2 = 2 * .253 * 3.86 = 1.95
