1. To make an uncharged object have a positive charge: A) remove some neutrons B) add some neutrons C) add some electrons D) remove some electrons E) heat it to cause a change of phase 2. A positively charged insulating rod is brought close to an object that is suspended by a string. If the object is repelled away from the rod we can conclude: A) the object is positively charged B) the object is negatively charged C) the object is an insulator D) the object is a conductor E) none of the above 3. Two protons (p 1 and p 2 ) and an eletron (e) lie on a straight line, as shown. The directions of the force of p 2 on p 1 , the force of e on p 1 , and the total force on p 1 , respectively, are: 4. The diagram shows the electric field lines in a region of space containing two small charged spheres (Y and Z). Then:
