2015年3月17日 · I'm a little confused by the formula used to find the charge between 2 charges. The formula is fe = kq1q2/r^2. How does this work for two objects such as a neutral object and a charged object? They are attracted to each other due to distribution of the charges, but the formula doesn't show that.

2018年9月27日 · Hi, I learned about how PE = U=kq1q2/r is the electrical potential energy for the system. It is found by taking the integral of electrical force and dr from infinity to the point of location we are interested in. So that is the intregral(F*dr) from r=inf to r=ro. My question is …

Question: Coulomb’s law has the form: F=kq1q2/r^2 k = 8.988 x 109 Newtons meter2/Coulomb2 The generic equation for a straight line is: y = mx + b “y” would correspond to what you have on

2016年9月12日 · F=(KQ1Q2)/r^2 • (r-hat) Why are we multiplying by r-hat? I understand that the equation helps us calculate the force between two charges. The book says that r=|r(bold)| I know that this is the magnitude sqrt(rx^2+ry^2+rz^2) rx= r with respect to the X position and so on. But we can neglect z since the charges are not in the k direction

E= KQ1Q2/r +B/rn K= 3x109 Vm/C, Q1 and Q2 are the charges associated with the ions. n is exponential that takes values between 7 and 13 and r is the radial distance between ions. Assuming the above potential is followed by Na+ and Cl- ions. determine: a. Equilibrium distance between ions b. Bond energy c. spring constant d. Max force required to

Coulomb's law F = kq1q2 / r ^ 2, for q1 = q2 = e, for the charge of the electron, and a distance r that varies from 0.5 armstrongs (1 X 10-10 m) to 1 nm (1 X 10-9 m), in increments of 0.5 armstrongs. As a point of reference, note that the radius of a small atom, such as the hydrogen atom, has a radius equal to half that of an armstrong.

Answer to Coulomb's law is F=kq1q2/r^2 where k=8.988x10^9. Your solution’s ready to go! Our expert help has broken down your problem into an easy-to-learn solution you can count on.

2003年12月10日 · The physical significance of the entire quantity, Ee=kq1q2/r, is precisely given by the definition of "electrical potential energy". You might be able to determine the physical significance by a "dimensional analysis" of the formula but you would really be asking "what is the physical significance of k".

2015年5月20日 · U=Eqd; U=kq1q2/r; V = Ed; V = kq1/r. The Attempt at a Solution I chose B but the correct answer is C. We know that the potential energy of a charge in an electric field is the force times the displacement: U = Eqd. What is the difference between answer choice B and C?

2023年3月31日 · If I have two different charges and I'm told to calculate net force, do I just use F=KQ1Q2/r^2 or Fnet=F1+F2... Please explain. If you have two charges at a distance 'r' then it is just F=KQ 1 Q 2 /r 2
