Well I know it has to be located further to the right. To find the Electric field from 2 charges... it wouldn't be as simple as using the equation E=Ke(q/r^2)?

Isnt the potential the energy required to move a charge in an electric field?

This was a question from a previous test and the work I have down is scrambled and makes little sense. Those were the equations I could pick out and I'm not even sure if I came up with my answer by working it through or I just picked an answer.

Homework Statement A 20 V emf is placed across 2 resistors in a series, a current of 2 A is present in each of the resistors. When the same emf is placed across the same 2 resistors in parallel, the current through the emf is 10 A. What is the magnitude of the greater of the 2 resistances...

Homework Statement How much energy is dissipated as heat over 2 minute time interval by a 1.5 k(ohm) resistor which has a constant 20 V potential difference across its leads? Homework Equations deltaV=-Ed The Attempt at a Solution In my notes this is the only equation that seems...

Homework Statement Point A (2,3)m and point B (5,7)m are in a region where electric field is uniform and given by E=(4i+3j)N/C. What is potential diff Va-Vb? Homework Equations Not a clue The Attempt at a Solution I tried converting the (4i+3j) into magnitude and that is as far...

Homework Statement A 40 uC charge is placed on x-axis at x=4cm. Where should a negative 60 uC charge be placed to produce a net electric field of zero at the origin? Homework Equations Fe=Ke((q1*q2)/r^2) The Attempt at a Solution I tried rearranging this equation to solve for r

Do I even need to know the values for the spring constant and masses?

So for this problem I need to find out what the mass of a single atom is?

Homework Statement A cube of side l rests on a rough floor. It is subjected to a steady horizontal pull F, exerted a distance h above the floor as shown below. As F increases, the block will either begin to slide, or begin to tip over and thus rotate. Determine the coefficient of static...

So I get sin^-1(.5)=30 divide the by w (1.63299) and I get the wrong answer (18.37117)

Haha. Had the numbers mixed up. Thanks

I got 20.043989 and I have no idea what the correct answer is supposed to be. I only have one more chance to get it correct

I did 2pi*73 rev/s and then multiplied it by my amplitude (.0437 m). Got it wrong.

Got it
