An electron is moving (at a particular instant) parallel to a wire with a speed of 3 x 10 m/s. The wire carries a current of 12 amps in the same direction as the electron moves. What is the force on the electron if it is 3 cm from the wire?
At t=0s a small "upward" (positive y) pulse centered at x = 6.0 m is moving to the right on a string with fixed ends at x=0.0m and x = 10.0 m . The wave speed on the string is 3.5 m/s .At what time will the string next have the same appearance that it did at t=0s?
Problem 3) An electron moving in a circle at a constant speed v has coordinates a(t) a cosut and y(t)- a sin ut, where a= 1 m. and u-wa=0.77c. The field point is located on the x-axis at position r=(2a,0,0). Take the speed of light to be c 3x 108 m/s. a) what are the coordinates of the electron at time t = 6.8 ns? b) If the time in part (a) represents the retarded time tr, what is the...

5. (a) Assume that an electron is moving along an x-axis with a speed of u = 3.080 x 10-m/s measured to a precision of 0.6%. What is the minimum uncertainty (as allowed by the uncertainty principle in quantum theory) with which you can simultaneously mea- sure the position of the electron along the c-axis? Note that the electron mass is m = 9.110 x 10-31 kg. (b) The speed of a bullet is known to a precision of 0.43%....
