a. What is the velocity of a beam of electrons that goes undeflected when passing through perpendicular electric field and magnetic field of magnitude 8.8x10^3 V/m and 7.5x10^-3 T, respectively? b. What is the radius of the electron orbit if the electric field is turned off? [hint: start with Newton’s 2nd law to derive an equation and then do the...

Two identical guitar strings are prepared such that they have the same length (0.65 m0.65 m) and are under the same amount of tension. The first string is plucked at one location, primarily exciting the first harmonic. The other string is plucked in a different location, primarily exciting the fourth harmonic. The resulting sounds give rise to a beat frequency...
