K = 1.29e-20 1.31e-20 J 2. 0.75/1 points Question: MI3 17.1.X.021 If the kinetic energy of an electron is 5.1e-18 J, what is the speed of the electron? (You can use the approximate (nonrelativistic) formula here.) v = 3346298.932 3.35e+06 m/s 3. 5.5/5.5 points Question: mi3 17.3.x.030.nva Locations A , B , and C are in a region of uniform electric field, as shown in the diagram above. Location A is at < -0.7 , 0, 0>m. Location B is at < 0.4 , 0, 0>m. In the region the electric field = < 750 , 0, 0> N/C. For a path starting at B and ending at A , calculate: (a) The displacement vector = < -1.1-1.1 , , > m (a) the change in electric potential: V = 825 825 volts (b) the potential energy change for the system when a proton moves from...
