Problem Seat 6 1. A charge A of +3 pC is placed on a line between two charges B of +1 yC and C of -4 pC. Charge A is 10 cm from B and 20 cm from C. What is the force on A. 540N A small charged pit ball is suspended 2 cm above the second charged pit ball resting on an insulated surface. If the charge of the lower ball is +20 statC and it has a mass of 0.25 g, what charge must be on the upper ball to lift the lower ball? 49stat C Each of two spheres is positively charged, the combined charge is 4 x 10 C, What is the charge of each sphere if they are repelled with a force of 27 x 10 N when placed 0.10 m apart. +1x10% +3 x 10% The electrostatic force between two like ions that are separated by a distance 5 x 10" mis 3.7 x 10 N. What is the charge on each ion? +3.206 x 10" Three +100 statC charges are arranged in straight line, the second charge B is 20 cm to the right of the first A and the third C is 50 cm to the right of A. a) What force is exerted by charges A and B on C? b) What force is exerted by A and C on B? 15.11 dyne towards C 13.89 dyne away from B
