3- (25 pts) As shown in the figure, a positively charged particle (q0, mass m0) is moving with a velocity V0 in the presence of both an electric field and a magnetic field. Electric field is generated by very large parallel plates. The potential difference between the two plates is 100 V. The particle is following a straight trajectory. Calculate the magnitude and the direction of the magnetic field between the plates. (Ignore gravitational interactions).

An electron accelerated from rest through potential difference V1 = 5 kV enters the gap between two parallel plates having separation d = 40 mm and potential difference V2 = 100 V. The lower plate is at lower potential. Assume the electric field between the plates is uniform and assume that the electron's velocity vector is perpendicular to the electric field vector between the plates. a. What is the direction of the uniform magnetic field (in unit of miliTesla) that allows the electron to travel in a straight line in the gap? (choose 1 for x direction, -1 for negative x direction, ±2 for ±y direction and ±3 for ±z direction.) b. What is the magnitude of this magnetic field (in units of mili-Tesla)?

Practice only: Instead of using the Electrostatic Analyzer to pick particles with a standard velocity, one may instead use a velocity selector depicted below. It uses both an electric field and a magnetic field together to provide a stream of particles with a particular velocity. The potential difference between the plates is 100 V and the distance between plates is 5 cm. If we want a positive point charge to pass through un-deflected and exit the plates with a velocity of 2 km/s, what strength magnetic field should we use (in T)? ( Draw all the forces on the particle when it's between the plates and use those forces to determine the answer)

A 150 V battery is connected across two parallel metal plates of area 28.5 cm2 and separation 9.20 mm. A beam of alpha particles (charge +2e, mass 6.64×10−27 kg ) is accelerated from rest through a potential difference of 1.75 kV and enters the region between the plates perpendicular to the electric field, as shown in (Figure 1).
