1. Any object produces an electrostatic field because it is built of charged particles such as protons and electrons. However, not all objects create a net electric field. Explain. 2. Charges produce electrostatic fields. Charges do not produce electrostatic forces. What is the condition under which an electrostatic force emerges? 3. The work-kinetic energy theorem (AKE = WNET) states that net -work done on an object of mass m changes the object's kinetic energy. a) Can the law apply to electric fields and motion of changes? b) What force does the work on changes? c) Formulate the law to find speed of a change q when a variable electrostic force F(x) acts on it.
