Homework Statement When asked for the electric field in flux and guassian surface-type questions I'm getting confused as to when the elecrtic field = 0. I thought that whenever I had a Gaussian surface (sphere, cylinder, box, etc), the electric field inside it would be 0, but I'm seeing...

Awesome. Just seemed too easy so I thought maybe something else was going on. Thank you

Ok. I already found the current in the circuit and I assumed that I needed to use Ohm's Law to find the voltage drop, but my question is whether I just multiply the current in the loop by the value for the specific resistor and that's it, or if I have to do something after that step?

Homework Statement Three batteries and four resistors are connected in a loop as shown (see attachment). What is the voltage drop across the top left resistor? Homework Equations V = IR The Attempt at a Solution This is part 3 of the 3 questions for this problem. On the other...

Thanks for your incredibly helpful and polite answer Einstein. I figured it out, it just confused me because I had done around 15 problems by the time I got to this one so I was exhausted. This forum has some really stuck up people if I may say so...

Homework Statement A cylindrical shell of radius 9.9 cm and length 286 cm has its charge density uniformly distributed on its surface. The electric field intensity at a point 23 cm radially outward from its axis (measured from the midpoint of the shell ) is 44800 N/C. Given: ke = 8.99 × 10^9...

With all due respect, the input actually helped me solve the problem properly

ha! I know, but the system wants the answer to six significant digits so I kind of have to keep EVERY digit up to the very end. I cannot thank you both enough for your help and quick responses. Thank you so much!

Oh! Thank You for catching that mistake. My answer now comes down to a final velocity of 871731.7804 m/s. Is this correct?

ohhhh! so the initial velocity in the x-direction would be: Vf = 0 + (4054368.932)(0.2) = 81087.37864 m/s and V = sqrt ((81087.37864)2 + (3.2x10^5)2) = 330113.8637 m/s ?

E=F/Q F=QE ma=QE a=(QE)/m=4054368.932 m/s^2 Vf=(3.2x10^5) + (4054368.932)(0.2) = 401087.3786 m/s The system is telling me this answer is wrong. Did I miss anything? I don't know if the problem is that the electric field is pulling in the x-direction while my initial velocity is in the...

Homework Statement A particle of mass 0.000103 g and charge 87 mC moves in a region of space where the electric field is uniform and is 4.8 N/C in the x direction and zero in the y and z direction. If the initial velocity of the particle is given by v_y = 3.2 × 10^5 m/s, v_x = v_z = 0, what is...

Thanks for the help but I found another post on another website that took me through the whole process which is what I needed to see how it was done instead of guessing randomly. THanks anyway

NOt sure... Still don't know how to set it up.

If my previous thread is correct, how do I get w_f ?
