In figure 2, an upwardly oriented uniform electric field E⃗ of a magnitude of 2.0 × 103 N / C has been established between two horizontal plates by charging the lower plate positively and the upper plate negatively. The plates have a length L = 10.0 cm, and they are at a distance of d = 2.0 cm. An electron is sent between the plates from the left end of the lower plate. The initial velocity ⃗v0 of the electron forms an angle θ = 45◦ with the lower plate, and its magnitude is 6.0 × 106 m / s (a) Will the electron touch one of the plates? (b) If so, determine which one. Then find how far horizontally from the left end the electron will strike.
When the nucleus of uranium-235 (92 protons and 143 neutrons) absorbs an additional neutron, it undergoes a process called nuclear fission in which it breaks into two smaller nuclei. One possible fission is for uranium nucleus to divide into two palladium nuclei, each of which has 46 protons and 5.9 x 10−15 m in radius. The palladium nuclei then fly apart (their separation if essentially infinite) due to their electric repulsion. If (immediately after the fission) we assume that the palladium nuclei are at rest and are just touching each other, what is their combined kinetic energy when they are very far apart? [Hint: Use the conservation of mechanical energy equation.]
What is the work required to rotate an electric dipole by 180º in a uniform electric field of modulus E = 46.0 N / C if p = 3.02 × 10-25C ∙ m and the initial angle is 64º?
