 a repelling force occurs between two charged objects when... charges are of like signs when a glass rod is rubbed with silk and becomes positively charged... electrons are removed from the rod if a positively charged glass rod is used to charge a metal bar by induction... the charge on the bar must be negative which sentence best characterizes electric conductors? they have electric charges that move freely when a charged body is brought close to an uncharged body without touching it, a(n) __ charge may result on the uncharged body. when a charged body is brought into contact with an uncharged body and then is removed, a(n) __ charge may result on the uncharged body. induced; residual if two point charges are separated by 1.5cm and have charge values of 2.0μC and -4.0μC, respectively, what is the value of the mutual force between them? 320N an alpha particle (charge 2C) is sent at high speed toward a gold nucleus (charge 79C). what is the electric force acting on the alpha particle when it is 2.0*10^-24m away from the gold nucleus? 91N four charges A, B, C, D are at corners of a square. Charges A and D, on opposite corners, have equal charge, whereas both B and C have a charge of 1.0C. if the force on B is zero, what is the charge on A? -0.35C two charges are located on the positive x-axis of a coordinate system. charge q1=2.00*10^-9C, and it is 0.02m from the origin. charge q2=-3.00*10^-9C, and it is 0.04m from the origin. what is the electric force exerted by these two charges on a third charge, q3=5.00*10^-9C, located at the origin? 1.4*10^-4N two point charges have a value of 30mC each and are 4cm apart. what is the electric field at the midpoint between the two charges? (k=8.99*10^9Nm^2/C^2) 0 N/C charges of 4.0mC and -6.0mC are place at two corners of an equilateral triangle with sides of 0.10m. at the third corner, what is the electric field magnitude created by these two charges? 1.6*10^6 N/C at what point is the electric field of an isolated, uniformly charged, hollow metallic sphere greatest? the sphere's outer surface if a conductor is in electrostatic equilibrium, the electric field inside the conductor is... zero if an irregularly-shaped conductor is in electrostatic equilibrium, charge accumulates... where the radius of curvature is smallest which of the following is not a characteristic of electrical potential energy? it results from a single chatrge two positive charges are initially separated by a distance of 2cm. if their separation is increased to 6cm, the resultant electrical potential energy is equal to what factor times the initial electrical potential energy? 1/3 a proton moves 10.0cm on a path parallel to the direction of a uniform electric field of strength 2.0 N/C. what is the electrical potential energy between the two charges? -4.8*10^-20 two protons are 2.0*10^-5m apart. what is the electrical potential energy between the two charges? 1.1*10^-23J four point charges are positioned on the circumference of a circle with a radius of 10cm. the charges are 0.5μC, 1.5μC, -1.0μC and -0.5μC respectively. if the electric potential at the center of the circle due to the 0.5 charges alone is 4.5*10^4V, what is the total potential at the center due to the four charges combined? 4.5*10^4V
