Conservation of energy in charge interactions PSS 21.1 Conservation of energy in charge interactions Prepare Identify the system involving the alpha particle. Then examine the forces acting within this sy whether mechanical energy is conserved. Make certain to draw a before-and-after visual ove symbols. Learning Goal: To practice Problem-Solving Strategy 21.1 Conservation of energy in charge interactions An alpha particle (a), which is the same as a helium-4 nucleus, is momentarily at rest in a region of space occupied by an electric field. The particle then begins to move. Find the speed of the alpha particle after it has moved through a potential difference of-3.45x10-3 v Part A Mechanical energy is conserved in the presence of which of the following types of forces Select all that apply. frictional magnetic electrostatic gravitational The charge and the mass of an alpha particle are da-3.20x10-19 C and ma-6.68x10-27 kg
