Question
1. A glass object receives a positive charge of +3 nC by rubbing it with a silk cloth. In the rubbing process have protons been added to the object or have electrons been removed from it? 2. Explain how a positively charged object can be used to leave another metallic object with a net negative charge. Discuss the motion of charges during the process. 3. Consider point A in in Figure CQ15.8 located an arbitrary distance from two point charges in otherwise empty space. a. is it possible for an electric field to exist at point A in empty space? b. Does charge exist at this point? c. Does a force exist at this point? 4. a. describe the motion of a proton after it is released from rest in a uniform electric field b. Describe the changes (If any) in its kinetic energy and the electrical potential energy associated with the proton.Explanation / Answer
1) Glass receives positive charge due to removal of electrons. Protons NEVER move because they are tightly bound in the nucleus of atoms. However, electrons are mobile and can move.
