F 1 exerted by q1 the force F 2 exerted by q2 and the force F 3exerted by q3 on Q separation distance on their velocities and on their accelerations In this Chapter we will the force acting. Conductors. Prof. Hugo . Beauchemin. 1. Introduction. We have seen most of the powerful concepts needed to understand electrostatics. W. e now turn to concrete applications, solving the equations. we saw for various types of system encountered in experiments . Electric Force. Whiteboard Particle Model . (remember sticky tape lab?). H. ow . you can . make a balloon stick on the wall?. What is occurring on the atomic level that lets you do this?. The atom. The atom has positive charge in the nucleus, located in the protons. . ital Equipment Corporation APTER 1 UNPACKING AND REPACKING ............................................. Cable Tie Removal 1nput'Voltage Range Selection ~nstallation .......................... Essential Knowledge. 1.B.2. : There are only two kinds of electric charge. Neutral objects or systems contain equal quantities of positive and negative charge, with the exception of some fundamental particles that have no electric charge.. If you rub a balloon . on . your . arm . more. , . the size of the charge will . ( decrease / increase ).. An object loses electrons and becomes . ( positively / negatively ). charged.. If . you charge two objects by rubbing them on your arm, they will have . Section 3. Method of Images. Plane interface between a semi-infinite (hence grounded) conductor and vacuum. e. a. What happens?. Find fictitious point charges, which together with given charges, make the conductor surface an equipotential (. phone for some research!. Do Now. In your notes:. Draw an atom of either Helium, Lithium, or Carbon. Label all the parts of your atom.. The first scientist to study these phenomena was Benjamin Franklin (1706-1790).. Tape lab (pt. 1). Make a tape “Flag”. Make a top (T1) and bottom (B1) tape sandwich. Make another pair of top and bottom tapes (T2 & B2). Directions. Hang T1 and B1 off the end of the table. (see figure below). Electrostatics. Study of electric charges that can be collected and held in one place.. Ben. Franklin. Electrostatics. Demonstrate how you can pick up the paper pieces without touching them in any way with your body.. . Electric Potential (Energy). Charges. The fundamental rule at the base of all electrical phenomena is that . like charges repel and opposite charges attract. An object that has unequal numbers of electrons and protons is . What is Electrostatics?. The study of stationary electric charges and electric fields. . - all ordinary matter contains both positive and negative charges.. . - most matter is electrically neutral because it. What makes up all matter?. What does it mean to be “charged”?. What are the (names &) methods of charging?. What do charged objects do?. What is GROUNDING?. What . are insulators & conductors?. Charges are conserved. Charges are additive in nature. Charges are quantised.. PROPERTIES OF ELECTRIC CHARGES. PRODUCTION OF ELECTRIC CHARGE. We can get electric charge by three ways. By friction or rubbing. Coulomb's Law : . Coulomb's Law states that the force between two point charges Q. 1. and Q. 2. is directly proportional to the product of the charges and inversely proportional to the square of the distance between them..
