A "point" charge of 2.3 x 10-12 C exerts a force on a "point" charge of 1.5 x 10-12 C situated 2.0 m away. What is the force exerted by the first charge on the second? O 1.6 x 10-14 N

Two identical conducting spheres are charged with a net charge of +2.0 q on the first sphere and a net charge of -4.0 q on the second sphere. The spheres are brought together, allowed to touch, and then separated. What is the total charge on the two spheres? a. +6.0 q b. +2.0 q c.-2.0 q d. -6.0 q  e. None of the above

Two charges, q1=-0.3mC and q2=--1.94mC are placed 12.02m apart from one another (mC stand for "milli-Coulomb").  What is the the electric force that q2 experiences due to the presence of q1?  Note, if the force direction is "to the left" be sure to include a negative sign.  If the direction of the force is "to the right", the force should be positive in sign.

In the figure,  charge q 1 = 2.0 × 10-6 C is placed at the origin and charge q 2 = -4.3 × 10-6 C is placed on the x-axis, at x = -0.20 m. Where along the positive x-axis can a third charge Q = -8.3 µC be placed such that the resultant force on this third charge is zero?

7 Two small objects each with a net charge of +Q exert a force of magnitude F on each other. F O 16 F O 4F We replace one of the objects with another whose net charge is +4Q. The original magnitude of the force on the +Q charge was F. What is the magnitude of the force on +Q now? O2F O F/4 OF +Q 000 000 F4 +Q +Q F5 F +4Q MacBook Air F6 ◄◄ F7 DII F8 F9
