3 points (a,b and c) and two identical positive charges. How do you find MAGNITUDE of the electric field at the 3 points? I just need to rank them, don't need numbers. all points are on the x-axis: A (x=0); charge +Q(x=1); B (x=3); c(x=4); charge+Q(x=5) (Picture attached in the 3rd post) 2. Relevant equations E= (1/4pie) (q/r^2) 3. The attempt at a solution I just focused on the r^2 since everything in the formula is the same. for point A: 1^2+ 5^2 = 26 Point B: 2^2+2^2 = 8 Point C: 1^2 + 3+2 = 10 so would B then have the greatest strength while A has the least?
