thanks again for the help. After reading over you last post it's very clear that the answer should be x=5 because it will keep increasing and 5 is the limit. The issue is that when I type 5 into the answer for "b) position of maximum force" on the webassign it is incorrect. Maybe the programming...
well Q1 =Q2
so looking at your fist post you said F=Q3*E(E being the added electric field of Q1 and Q2) so
I think the issue is how do I find "E here is the net field produced by Q1 and Q2 ,note that you need to do vector addition)"
im sorry I'm getting confused. I realize that Q1 and...
so for the vertical component...
(8*10^-19)*-(d2/sqrt(x2+d2))(kQ1/sqrt((.342+x2)2)+(d2/sqrt(x2+d2))(kQ2/sqrt((.342+x2)2)))
and the horizontal...
(8*10^-19)*(x2/sqrt(x2+d2))(kQ1/sqrt((.342+x2)2)+(x2/sqrt(x2+d2))(kQ2/sqrt((.342+x2)2)))
but how do I solve for maximizing x...
(8*10^-19)*(-sin(theta)(kQ1/sqrt((.342+x2)2)+sin(theta)(kQ2/sqrt((.342+x2)2)))
is that correct since the E of Q1 would be down and E of Q2 would be up? How would I find theta though?
Homework Statement
In Fig. 21-29, particles 1 and 2 of charge q1 = q2 = +4.80*10^-19 C are on a y-axis at distance d = 34.0 cm from the origin. Particle 3 of charge q3 = +8.00*10^-19 C is moved gradually along the x-axis from x = 0 to x = +5.0 m. At what values of x will the magnitude of the...
isn't that what I did in my attempt at a solution? the only other thing I realize is that the force of gravity is 2r not r. so m(v^2/r)=GMm/(2r^2). Do I need two separate equations for both stars?
[b]1. In a double-star system, two stars of mass 6.0 *10^30 kg each rotate about the system's center of mass at a radius of 2.0 * 10^11 m.
(a) What is their common angular speed?
(b) If a meteoroid passes through the system's center of mass perpendicular to their orbital plane, what minimum...
