Draw a picture of the crt with an undeflected electron beam. since you will not be using electric fields, you do not need to include the deflection plates. draw a coordinate axis on this sketch and show a region occupied by a uniform magnetic field for part of the electron’s trajectory. determine the direction of this magnetic field to give maximum deflection. draw the electron’s path entering, through, and leaving this region of uniform magnetic field to show the beam deflection at the screen. also show vectors representing the electron’s velocity and acceleration in each part of the path.

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?

A1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. the spring has an undeformed length of 5 in. and a constant k =25 lb/ft. knowing that the collar is released from being held at a determine, the speed of the collar and the normal force between the collar and the rod as the collar passes through b.
