ok! SO I figured it out! You use pathagoreum Theorem and you end up getting that B= 0.9756 T I pluged that in and got the answert to be: 2.13 e-3 N NOW though I don't understand what they are asking for when they ask: What is the direction of the magnetic force on the particle relative to...

Homework Statement A particle with a charge of 35.7 uC moves with a speed of 61.1 m/s in the positive x direction. The magnetic field in this region of space has a component of 0.527 T in the positive y direction, and a component of 0.820 T in the positive z direction. What is the magnitude...

Thank you! I can't believe I saw that equation as having everything in the denominator! Thank you!

No I thought that was the equation, at least that is the one on my physics book? Is there another equation to find the speed of an electron?

Homework Statement An electron with kinetic energy 1.60 keV circles in a plane perpendicular to a uniform magnetic field. The orbit radius is 24.0 cm. a Find the speed of the electron. b Find the Magnetic Field Homework Equations k=1/(2mv^2) B=mvqr The Attempt at a Solution I...

The distance would be 16.58 cm = 0.166 m So plugging that into the proportion equation: I2/R2=I1/R1 11.5A/.0588m = I1/0.166m I1= 32.5A Ok I think I forgot to change the cm to meter the first time! But thank you for your help!

The velocity will point in the negative Y direction according to the right hand rule. The equation comes from: netForce= qE-qvB And when you plug all the values in i keep getting: 184.8 m/s but my computer says it is wrong.

Homework Statement Two straight parallel wires carry currents in opposite directions. The wire on the right carries a current of I2 = 11.5 A. Point A is the midpoint between the wires. The total distance between the wires is d = 10.7 cm. Point C is 5.88 cm to the right of the right wire...

Homework Statement A 6.45 uC particle moves through a region of space where an electric field of magnitude 1220 N/C points in the positive direction, and a magnetic field of magnitude 1.19 T points in the positive z direction. If the net force acting on the particle is 6.45E-3 N in the...

OK I keep getting it wrong so I now tried: P=I^2*R I did 0.345ohms/km * 173 km= 59.685 Then I did P=I^2*R to get> (1.05kA*1.05kA)*(59.685ohms)= 65.8 kW BUT it keeps telling me I am WRONG! PLease help!

Homework Statement A high-voltage transmission line with a resistance of 0.345 ohms /km carries a current of 1.05 kA. The line is at a potential of 600 kV at the power station and carries the current to a city located 173 km from the power station. A>What is the power loss due to...
