Two particles of the same mass carry charges +3Q and –2Q, respectively.  They are shot into a region that contains a uniform electric field as shown.  The particles have the same initial velocities in the positive x-direction.  The lines, numbered 1 through 5, indicate possible paths for the particles.  If the electric field points in the negative y-direction, what will be the resulting paths for these particles? choices: path 5 for +3Q and path 1 for –2Q     path 5 for +3Q and path 2 for –2Q     path 4 for +3Q and path 1 for –2Q     path 4 for +3Q and path 2 for –2Q

Newer automobiles have filters that remove fine particles from exhaust gases. This done by charging the particles and separating them with a strong electric field. Consider a positively charged particle + 1.5uC that enters an electric field with strength 4 x 10^6 N/C. The particle is traveling at 15 m/s and has a mass of 10^-9 g. What is the acceleration of the particle ? (Enter the magnitude only) 2.) what is the direction of the acceleration of the particle relative to the electric field?

On a typical clear day, the atmospheric electric field points downward and has a magnitude of approximately 110 N/C. Compare the gravitational and electric forces on a small dust particle of mass 3,1 x 10 g that carries a single electron charge. 1.1134 What is the acceleration (both magnitude and direction) of the dust particle? (Enter the magnitude in m/s.) magnitude m/s direction downward v

In the ever popular game from the future, Electrodisc, players can score double points by pushing a disc into another disc with the electric field generated by a third disc. The discs are by regulation 1 kg. All discs have the same shape and are made of the same conducting material. In the figure below, disc 1 is held in place, and disc 2 is held stationary 4.1 m from disc 1 by a player. The player then releases disc 2. 10 m. F12 What is the initial magnitude of the acceleration imposed on the second disc? The charge on the first disc is 1.7 mC. The charge on the second disc is 1.7 mC. The charge on the third disc is neutral. m/s² Later, discs 2 and 3 touch and charge is exchanged. How much charge is exchanged once the charges on each disc reach an equilibrium? mC After charge is exchanged, what is the direction of the force on disc 3 due to disc 2? O toward the left O toward the right O upward O downward

Two 4.0 kgkg masses are 1.0 mm apart on a frictionless table. Each has 1.0 μCμC of charge.     Part A What is the magnitude of the electric force on one of the masses?   Part B What is the initial acceleration of each mass if they are released and allowed to move? Express your answer in meters per second squared.
