Use the following information to answer the next question. Two small metal spheres are fixed to insulated stands and given static charges of -4.00 x 10^-6 C and +2.00 x 10^-6 C, respectively. The spheres are then placed 0.500 m apart. Point P is halfway between the charged spheres. 13. At point P, the magnitude of the electric field caused by the two charged spheres is A. 8.63 x 10^5 N/C B. 2.88 x 10^5 N/C C. 2.16 x 10^5 N/C D. 7.19 x 10^4 N/C

The formula for the electric field E due to a point charge q at a distance r is given by: E = k * |q| / r^2 where k is Coulomb's constant, which is approximately 8.99 * 10^9 N m^2/C^2. Since point P is halfway between the two spheres, the distance from each Show more…

Two charged spheres are 5.00 cm apart: One sphere has a charge of 2.50 x 10^-4 C and the other sphere has a charge of 3.20 x 10^-5 C. Assuming k = 9.00 x 10^9 Nm^2/C^2, the electric force between the two spheres is: a) 1.44 x 10^1 N b) 2.25 x 10^19 N c) 4.44 x 10^-18 N d) 2.88 x 10^4 N

The initial charges on the three identical metal spheres in the figure below are as follows: sphere A, Q; sphere B, -Q/8; and sphere C, Q/4, where Q = 5.00 × 10^-14 C. Spheres A and B are fixed in place, with a center-to-center separation of d = 3.2 m, which is much larger than the spheres. Sphere C is touched first to sphere A and then to sphere B and is then removed. What is the magnitude of the electrostatic force between spheres A and B?

The initial charges on the three identical metal spheres in Fig. $21-24$ are the following: sphere $A, Q ;$ sphere $B,-Q / 4 ;$ and sphere $C, Q / 2,$ where $Q=2.00 \times 10^{-14} \mathrm{C}$ . Spheres $A$ and $B$ are fixed in place, with a center-to-center separation of $d=1.20 \mathrm{m}$ , which is much larger than the spheres. Sphere $C$ is touched first to sphere $A$ and then to sphere $B$ and is then removed. What then is the magnitude of the electrostatic force between spheres $A$ and $B ?$
