A plastic rod that has been charged to -14 nC touches a metal sphere. Afterward, the rod's charge is -4.0 nC. ▼ 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? ▸ View Available Hint(s) O electrons, from the rod to the sphere O electrons, from the sphere to the rod Oprotons, from the rod to the sphere O protons, from the sphere to the rod Submit Part B How many charged particles were transferred? ▸ View Available Hint(s) N= VA24 h A B ? particles

Two positive charges, each of magnitude q, are on the y-axis at points y= ta and y=-a Where would a third positive charge of the same magnitude be located for the net force on the third charge to be zero? a. at the origin b. at y= 2a c. at y=-2a d. at y= -a

Suppose you have a glass rod with a 0.68 μC charge and a polyester cloth with a -0.61μC charge, which are 13 cm apart.   What is the magnitude of the attractive force between them (in N), using the approximation that they act like point charges? Numeric   : A numeric value is expected and not an expression. | F | = ________
