- F = kQq R2 finding force problem - Physics Forums
Two charges Q1 amd Q2 jabe a force of 3 1x10^-8 N when the distance between them is 3m Use the formula F = kQq R2 to determine the force when the distance
- What is Q in kQq r? (+Ze) Explained • Physics Forums
What is Q in kQq r ?? Hey guys the textbook says Q is (+Ze) and q is (+2e) the later is 2 times the positive equivalent of an electron's charge Though the former I'm unable to make any sense of, what is Ze?? Thanks Cheers!
- How Can You Determine Coulombs Constant from a Force vs. Distance . . .
Homework Statement Determining Coulomb's constant through a force vs separation distance graph Homework Equations F = kqQ r^2 The Attempt at a Solution So, I'm a little confused about what I should do! We were shown a video of two charges moving towards each other We were
- How Do You Solve for Charges Using Coulombs Law Equation?
Homework Statement Homework Equations F=kQq d^2 The Attempt at a Solution I've tried working on this for two days and can't figure it out In (a), the cumulative force on A is the sum of the force from B and the force from C or: F=\\frac{k Q_a Q_b}{d^2} + \\frac{k Q_a
- Question about common math operations. - Physics Forums
Then we can say that E = KQq (R^2 q) No, we can't say this It's really E = (KQq R^2) q, which is the same as (KQq R^2) * (1 q) The order in which you do the division is significant It might be easier to see formatted as it usually is in print The q factors cancel because you have one of them in a numerator and the other in a denominator
- Electric Potential Difference and charges • Physics Forums
The discussion revolves around calculating the electric potential energy of four identical charges (+3 5 µC each) positioned 0 35 m apart The initial attempts involved summing the potential energies of all possible charge combinations using the formula U = kqq r, but the results were incorrect due to double counting A suggestion was made to divide the total by two to correct for this
- What is K in K=1 4pi Epsilon 0? • Physics Forums
So here's a formula they teach us to use: 1 2mv2= kQq r What is k called? what is the name of this constant, and what is it equal to since I was told it was the electric constant and went about solving it with that value, but at the back in the answer section they used the value 9x10^9! Thanks guy! :D Physics newson Phys org
- Electric Charges (Quick Question) - Physics Forums
Can some one please explain to me why charged particles attract neutral ones, yet if you place the numbers into the equation Ep=-kQq r, it will show you that there is no potential energy between a charged particle and a neutral one, because one of the Q's will be 0 How does this make sense
