Unformatted text preview: 1 q(3q ) 1 6q 2 = , toward the lower the left charge. The other 40 ( L 2 ) 2 40 L2 two forces are equal and opposite. 21.75: a) F = + b)The upper left charge and lower right charge have equal magnitude forces at right angles to each other, resulting in a total force of twice the force of one, directed toward the lower left charge. So, all the forces sum to: 2 1 q (3q) 2 q (3q ) = q 2 3 2 + 3 N. F= + 40 L2 2 ( 2 L) 2 40 L ...
