but how di i find r

m*(2pi/t)/r= Bq

2pie

so s=360 T= 5.24×10-11 s

velocity, but how do i find that out from what i know

ω = θ / t (2a) where ω= angular velocity (rad/s) θ = angular displacement (rad) t = time (s)

kinetic engergy 1/2mv ______ r

just one V is i am solving for b and the only thing i know is what is at the begging

Homework Statement A magnetron is a microwave source in which a "bunch" of electrons travel on a circular orbit in a uniform magnetic field. As the electrons pass the electrodes, a high-frequency alternating voltage difference occurs. Suppose the resonant frequency is f = 1.91×1010 s−1...

Homework Statement A capacitor is charged to 1 coulomb; the capacitance is 6.00×10-5 farads. Then a switch is closed which puts the capacitor in a closed circuit with a resistor; the resistance is 9.20×10^1 ohms. Calculate the charge on the capacitor after 4.00 milliseconds. (1 ms = 0.001 s)...

I have the same problem but with these numbers A capacitor is charged to 1 coulomb; the capacitance is 6.00×10-5 farads. Then a switch is closed which puts the capacitor in a closed circuit with a resistor; the resistance is 9.20×101 ohms. Calculate the charge on the capacitor after 4.00...
