other charged object experiences a force of 0.15N. What is the charge of the other object? 3.33µC1) Three charges are fixed on the ends of insulating rods as show in the diagram. Charge A has a charge of +6µC (where µ means “micro” and mathematically is x10-6), charge Bhas a charge of -4µC, and charge C has a charge of +8µC. a) Find the net force and direction acting on charge B. 3N @ 306.87ºb) Find the net force and direction acting on charge C. 1.12N @ 112º2) A block with mass 2kg and charge of 1.5x10-5C is located near a fixed (stuck where it is) charge of the same amount. The block is resting on the floor. The coefficient of static friction is 0.827. How close can you place the block before it starts to slide? 0.35m3) In a Hydrogen atom, the electron orbits the single proton in the center of the atom. They both have the same charge (1.6x10-19C). The electron, mass 9.11x10-31kg, orbits the proton at a distance of 5.3x10-11m. What is the orbital speed of the electron? 2.18x106m/s4) 5x1012electrons are placed on a metal sphere that is 0.4m away from another charged object. The other charged object experiences a force of 0.15N. What is the charge of the other object? 3.33µC
