Homework Statement The figure shows a vertically polarized radio wave of frequency 1.0 times 10^6 traveling into the page. The maximum electric field strength is 1000V/m. What is the maximum magnetic field strength? What is the magnetic field strength at a point where E=500V/m down What is...

Homework Statement What is the magnitude of the force on the proton in the figure? View Figure Homework Equations F=q(E+v*B)The Attempt at a Solution Ive tried just putting the numbers into that equation provided and it doesn't work so I am guessing there is some more that I am missing. I've...

No need to help me on this problem I figured it out I didn't notice the rms on the voltage so I forgot to multiply by square root of 2

Homework Statement An inductor is connected to a 15 kHz oscillator. The peak current is 65 mA when the rms voltage is 6.0 V. What is the value of the inductance L? In mH Homework Equations Il=Vl/Xl Xl=frequency*L The Attempt at a Solution Well I thought this problem was really...

Homework Statement The loop in the figure is being pushed into the 0.20 T magnetic field at 50 m/s. The resistance of the loop is 0.10 ohm. Homework Equations I=E/R E=|dmagnetic flux/dt| The Attempt at a Solution I don't know how to even start this problem all the examples give...

ok got it thanks for the help.

Homework Statement A long, straight conducting wire of radius R has a nonuniform current density J=J0*r/R, where J0 is a constant. The wire carries total current I. Find an expression for J_0 in terms of I and R. Find an expression for the magnetic field strength inside the wire at radius r...

I can't find any equations in my book for turns in the loop so if you could help me out with that Id appriciated it and I was wondering that myself as for the picture it is set up as a rectangular loop so I wasn't sure that the turns ment anything and wouldn't it make the sin of theta 90 degrees?

Homework Statement The 10-turn loop of wire shown in the figurelies in a horizontal plane, parallel to a uniform horizontal magnetic field, and carries a 2.0 A current. The loop is free to rotate about a nonmagnetic axle through the center. A 50 g mass hangs from one edge of the loop...

How would I find the charge on the Mercury. Wouldn't it have a neutral charge or 0 with 80 electrons and protons and even if it is a charged state which state would it be?

I can calculate the Kinetic energy of the proton but I don't know how to figure out how close that will allow me to get to the mercury atom.

Homework Statement A proton is fired from far away toward the nucleus of a mercury atom. Mercury is element number 80, and the diameter of the nucleus is 14.0 fm. If the proton is fired at a speed of 4.0 times 10^7, what is its closest approach to the surface of the nucleus? Assume the nucleus...

Homework Statement What is the net electric flux through the torus (i.e., doughnut shape) of the figure Homework Equations net flux= E*A I believe is needed The Attempt at a Solution I don't know how to do this problem at all. I feel like I don't have enough information to...

Homework Statement A 2.40 -mm-diameter glass sphere has a charge of + 1.70 nC. What speed does an electron need to orbit the sphere 1.40 mm above the surface? Homework Equations Electric Field of Sphere: E=k*Q/(r^2) q*E=M*v^2/r The Attempt at a Solution It seems pretty straight...

I tried doing that but I must of misunderstood you because it still tells me I am wrong. I did 10cm/80cm * 2pi and this is still wrong.
