19.4.1. Activity: "Reading" the Coulomb Equation a. Draw the direction of the unit vector in the diagram below. Note: The direction of this vector does not depend on the signs or the mag- nitudes of the charges. 9B b. In the table below, indicate the sign of the product of each combination of positive and/or negative charges. 2610 mal sil Sign of A + + Sign of 9B Sign of 9A-9B + 9A and q for c. Use an arrow to indicate the direction of the force exerted by on B if the charges are both positive or both negative. 9B WAJ 2'8MOJUCO NO MOITAJUMRO QA AM lo sbingem ad te d. Use an arrow to indicate the direction of the force exerted by A on qB if the charges have opposite signs (that is, one is positive and one is negative). of ai bna amordi odt maswind smile gnole SIA angie salilovedovaluqe bus angia etianggo over bols or excesos dugniwollol coltsupe edr yd f 9B 9A sub AP no bans
