An electron traveling horizontally with velocity 1.55 x10^{5} m/s enters a region where a uniform magnetic field is directed into the plane of the paper as shown. The electron has a mass of 9.11 x10^{-31} kg and a charge of -1.60 x10^{-19} C. The particle then enters a uniform 1.60-T magnetic field. If the particle's velocity is perpendicular to the magnetic feild at all times.
a). Describe and sketch the motion of the electron once it has entered the field on the paper. Identify the direction of the force acting over the electron.
b). What is the magnitude of the magnetic force exerted on the particle?
A Wheatstone bridge is connected to a nine volt battery and is balanced when R1 = 6.3 k?, R2 = 3.3 k?, and R3 = 9.7354 k?
A 36.0 g bullet moving at 478 m/s strikes a 3.7 kg bag of flour that is on ice, at rest. The bullet passes during the bag, leaving at 255 m/s. How fast is the bag moving when the bullet exits.
what speed will the dart leave the gun.
During a fun run a girl runs for 12 s moving 2.7 m/s. She then accelerates at 0.5 m/s^2 over the next 25 m. she then runs at her new speed for 10s. What distance did she cover during the entire period?
Two hockey players strike a puck of mass 0.169 kg with their sticks simultaneously, exerting forces of 1.17 103 N, compute the instantaneous acceleration of the puck
In soccer, a speed record was set for kicking a soccer ball at 43m/s. If the soccer player kicked the ball from ground level at an angle of 30° from the horizontal, what would be the flight time of the soccer ball? Assume that air resistance is ne..
A village maintains a large tank with an open top, containing water for emergencies. The water can drain from the tank through a hose of diameter 6.65 cm. The hose ends with a nozzle of diameter 2.50 cm. A rubber stopper is inserted into the nozzl..
What is the linear speed of the hoop's center of mass just as the hoop leaves the incline and rolls onto a horizontal surface
A parallel plate capacitor has plates of area 2.0*10^3 and plate separation 1.0*10^4m. find the capacitance of this system if air fills the volume between the plates.
A pendulum consists of a 4.98kg mass on the end of a 0.873 m string. The mass is pulled aside so the string makes an initial angle with the vertical of 12.5o. The mass is then released with initial speed of 2.10m/s upward and perpendicular to the rop..
