A glass rod that has been charged to +12 nC touches a metal sphere. Afterwards, the rod’s charge is +8.0 nC.   a) What kind of charged particle was transferred between the rod and the sphere, and in which direction? That is, did it move from the rod to the sphere or from the sphere to the rod? b) How many charged particles were transferred?

Two charges +4 µC and +11 µC are placed along the x axis, with the first charge at the origin (x = 0) and the second charge at x = +1 m. Find the magnitude and direction of the net force on a -9 nC charge when placed at the following locations below. Overall Hint Review Section 5.3 Coulomb's Law. Use Coulomb's Law to calculate force due to each of two charges and add them together for the net force, minding the directions. For part (c), you will need to do the vector sum (more below). a. halfway between the two charges: magnitude of force is direction is Select an answer b. on the x axis at x = -0.5 m: magnitude of force is direction is Select an answer c. at the coordinate (x, y) = (1 m, 0.5 m) (half a meter above the +11 µC charge in a direction perpendicular to the line joining the two fixed charges): Hint for (c) Magnitude of force is degrees below -x axis. mN, and the direction is mN, and the mN, and the

What is the net force (magnitude and direction) that the charges at vertices B and C?

hw 4 Three charges are located as shown in the figure, with values q1 = 4.2 × 10-16 C, q2 = -1.6 × 10-16 C, q3 = 6.75 × 10-16 C. The charges are separated by d1 = 2.9 × 10-6 m and d2 = 4.2 × 10-6 m. What is the force of q2 on q1 in the x direction, Fx? Give your answer in newtons, and recall k = 8.988 × 109 N m2/C2.  What is the force of q3 on q1 in the y direction, Fy? Give your answer in newtons.

Two particles A and B with charges of +16 C and +36 C are separated by a distance of 4 cm. If C is a point that lies between A and B such that the field strength at C is zero. The location of C from A (in cm) is…. OptionA. 1.2B. 1.4C. 1.6D. 1.8E. 2.0 Please answer fast max 15-20 minutes thank u
