Electrostatic forces are conservative. This means that mechanical energy (KE +PE) is constant or conserved in absence of other dissipative forces such as friction. If a charged particle moves from point A to point B in an electric field (assume that dissipative forces such as friction are absent), select all the statements that are true. The symbol A represents the change in the particular quantity. Recall what does positive and negative work mean? Reflect on what the negative sign represents in each case? Select multiple answers. ΔΚΕ + -ΔΡΕ changes in KE and PE are not connected. ΔΚΕ = −ΔΡΕ i.e., if KE increases, PE decreases and vice-versa APE = WorkAB i.e., for positive work, PE increases and for negative work, PE decreases ▲PE = −Workä→B i.e., for positive work, PE decreases and for negative work, PE increases
