Homework Statement If the inductance and the capacitance both double in an LRC series circuit, the resonant frequency of the circuit will... decrease to 1/4 its original value decrease to 1/2 its original value decrease to 1/8 its original value Homework Equations The Attempt at a...

Homework Statement A circular loop of wire is rotated at constant angular speed around an axis whose direction can be varied. In a region where a uniform magnetic field points straight down, what must be the orientation of the loop's axis of rotation if the induced emf is to be zero...

Homework Statement Charge A has 10 electric field lines coming out, Charge B has 20 lines coming out, and Charge C has 30 lines coming in. Which pair of these charges will have the largest force between them if placed one cm apart? Homework Equations The Attempt at a Solution Is...

Yup I completely understand why you set it up like that...thanks!

Oh wow thanks :)...I see now...So I end up with... Ea = K*A/R1^2 Eb = K*B/(R-R1)^2 A/R1^2 = B/(R-R1)^2 And I solve for R1??

I don't get it lol...I'm sorry...

So I just use R?

Oh I thought the distance was just the distance between A and B...but its the distance from point A to the point where the electric field and same for B?

Homework Statement Two point charges are placed along a horizontal axis with the following values and positions: +3.0 �C at x = 0 cm and -7.0 �C at x = 20 cm. At what point along the x-axis is the electric field zero? Homework Equations The Attempt at a Solution Can I just set Ea...

Well yea but I don't have R2? So I tried using like R2 = 3- R1 but I can't get that to work...

Homework Statement Charge A and charge B are 3.00 m apart, and charge A is +2.00 C and charge B is +3.00 C. Charge C is located between them at a certain point and the force on charge C is zero. How far from charge A is charge C? Homework Equations The Attempt at a Solution I am...

WOO-HOO LOL Thank you...I think I got it from here :)

A = 1 and B = -1

So is it just... 2 = A(2n+1) + B(2n-1)
