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.

The ability to make things happen is also called a. heat b. force c. matter d. energy

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j. b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Athird point charge q3 is now positioned halfway between q1 and q2. the net force on q2 now has a magnitude of f2,net = 5.861 n and points away from q1 and q3. what is the value (sign and magnitude) of the charge q3?
