    Coulomb's Law and the net electric field

    1. Homework Statement Two point charges q1 = -5.60 nC, and q2 = -14.0 nC are separated by 25.0 cm (see figure below). http://www.webassign.net/yf12/21-p-031-alt.gif (a) Find the net electric field these charges produce at point A magnitude 10360 N/C direction is to the right (b)...

    Coulomb's Law and net electric field

    I'm still not quite sure where you're going with that. I tried a couple things but I ended with the wrong answer..

    How Does Coulomb's Law Apply to a Charged Ring and a Point Charge?

    Homework Statement A ring-shaped conductor with radius a = 2.20 cm has a total positive charge Q = +0.145 nC uniformly distributed around it, as shown in the figure below. The center of the ring is at the origin of coordinates O. (a) What is the electric field (magnitude and direction) at...

    How Much Force Can a Human Femur Withstand Before Fracturing?

    Homework Statement Assume that Young's Modulus for bone is 1.50 X 10^10 N/m2 and that the bone will fracture if more than 1.50 X 10^8 N/m2 is exerted. (a) What is the maximum force that can be exerted on the femur bone in the leg if it has a minimum effective diameter of 2.60 cm? (b)...

    Find the tension in the wire and the components of the force exerted

    well its right, I stated in one of my other posts that the numbers were exactly what my actual problem contained. the 720 N of the bear is actually 740, which is why when I added all the numbers up I got 1020 instead of 1000.. So in the end the force is equal to 720 Sorry for all the confusion

    Find the tension in the wire and the components of the force exerted

    Yea forget what I just said, I had a brain fart for a second there lol Its just 720, sorry about the confusion. Thanks again!

    Find the tension in the wire and the components of the force exerted

    Ok well the numbers in that question aren't actually my exact numbers, but with my numbers I come out with: Rsin(theta) = 720.65 would that mean that its: Rsin(60) = 720.65 R = 832.13 So 832.13 would be the force in the y-component?? I only have one more guess left on my homework...

    Find the tension in the wire and the components of the force exerted

    So would it go like 345.66cos(60) - 1020 = 0 ??

    Find the tension in the wire and the components of the force exerted

    would this be closer to the y-component for the force? Rsin(theta) = 720 + 200 + 80 - 345.66sin(60)

    Find the tension in the wire and the components of the force exerted

    Homework Statement A hungry bear weighing 720 N walks out on a beam in an attempt to retrieve a basket of food hanging at the end of the beam. The beam is uniform, weighs 200 N, and is 5.40 m long; the basket weighs 80.0 N. a) When the bear is at x = 1.00 m, find the tension in the wire and...
