An electron (-q= +1.602 × 10-¹9) moves along a straight line from point b with a separation distance of 0.2 m.Considering the electric field along this line is uniform with magnitude of E=300 N/C and directed from points a to b.What is the magnitude of force electron?
A particle with a charge of +5.90 nC is in a uniform electric field E directed to the left.It is released from rest and moves to the left; after it has moved 60.0mm,it's kinetic energy is found to be +3.50 × 10-⁶.What is the potential difference of the starting point with respect to the end? What is the magnitude of electric field?
A particle of charge 3 x 10-9 C is located at point (0,0) in a certain coordinate system. Assuming all lengths are in meters, calculate the potential at the following points: A (3,3) and B (0,2). How much work is needed to take a particle of charge 2 x10-5 C from point A to point B?
You are spending the summer working for a chemical company. Your boss has asked you to determine where a chlorine ion of effective charge -e would situate itself near a carbon dioxide ion. the carbon dioxide is composed of 2 oxygen ions each with an effective charge of -2e and a carbon ion with an effective charge +3e. These ions are arranged in a line with the carbon ion sandwiched midway between the two oxygen ions. The distance between each oxygen ion and the carbon ion in 3.0 x 10^-11 m. Assuming that the chlorine ion is on a line that is perpendicular to the axis of the carbon dioxide ion and that the line goes through the carbon ion, what is the equilibrium distance for the chlorine ion relative to the carbon ion on this line? For simplicity, you assume that the carbon dioxide ion does not deform in the presence of the chlorine ion. Looking in your trusty physics textbook, you find the charge of the electron is 1.60 x 10^-19 C.
1.An electron has an energy of 2.3 ev. What is the energy of the electronic in J?
