An electron beam is fired along x axis at a speed of 2.3 x 105 m/s to a space where there is a magnetic field of strength 0.40 T that lies along -z axis. Calculate the value and direction of magnetic force on the proton beam.

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0° north of east. the plane then flies to town b, located d2 = 230 km at 30.0° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)
