1.c The drawing shows three point charges fixed in place. The charge at the coordinate origin has a value ofq₁= +9.36C; the other two have identical magnitudes, but opposite signs:q₂= -6.23C andq₃= +6.23C.(a)Determine the net force exerted onq₁by the other two charges.(b)Ifq₁had a mass of 1.50 g and it were free to move, what would be its acceleration?

a.

b.

1a. In a vacuum, two particles have charges ofq₁andq₂, whereq₁= +3.1C. They are separated by a distance of0.38m, and particle 1 experiences an attractive force of3.4N. What is the value ofq₂, with its sign?

1b. The drawings show three charges that have the same magnitude but may have different signs. In all cases the distance d between the charges is the same. The magnitude of the charges is |q|=7.0 ?C, and the distance between them is d=4.0 mm. Determine the magnitude of the net force on charge 2 for each of the three drawings.
