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.

Avolcano erupts next to a grassland area in a valley. a. describe three ways in which material released by the volcano could impact the grassland area. b. describe three ways in which the grassland ecosystem could recover after a volcanic eruption.

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
