Math Connections Force and Motion Name: Date: Electric Forces larged objects exert electric forces on one another. These forces are different from gravitational ces and originate from charged particles. In general, the magnitude of the electric force depends on the strengths of the charges and the distance between the charged objects. The stronger the ectrical charges, the stronger the electric force; the greater the distance between the charged jects, the weaker the electric force. The relationship between the charges, the distance between : charges, and the electric force can be expressed mathematically by Coulomb's law. Fe = k (9192 ) d2 here: F. is the electric or electrostatic, force (N) between two charged objects; k is Coulomb's constant (8.99 x 109 N x m2/C2); q, and q, are the quantities of the electrical charges of the two different objects in C; and d is the distance between the two charged objects in meters. Find the electrostatic force between two protons that are 200 cm apart. The elementary charge of a proton is 1.602 x 10-19 C. Two balloons tied to the back of the birthday boy's chair are 100 mm apart. Find the electrostatic force between the two balloons, given that each balloon carries a charge of 4.6 MC (1 HC = 1x 15-C). 4.6x10-C Two equally negatively charged spheres are placed close to each other. If the distance between the two spheres is tripled, by what factor does the force acting between the spheres decrease
