Three questions. Please answer with all work used to find the answers.
(1)Two equally charged, 3.549 g spheres are placed with 2.925 cm between their centers. When released, each begins to accelerate at 320.079 m/s2. What is the magnitude of the charge on each sphere?
(2)Object A, which has been charged to +12.39 nC, is at the origin. Object B, which has been charged to -25.5 nC, is at x=0 and y=2.07 cm. What is the magnitude of the electric force on object A?
(3)A 5 cm spring is suspended with a mass of 3.8589 g attached to it which extends the spring by 1.5747 cm. The same spring is placed on a frictionless flat surface and charged beads are attached to each end of the spring. With the charged beads attached to the spring, the spring's extension is 0.0116 m. What are the charges of the beads?
An asteroid of mass 4.4 x 104 kilogram carrying a negative charge of 19.2 μC is 130 meter from a second asteroid of mass 6.8×104 kilogram carrying a negative charge of 25.0 μC. Find the net force the asteroids exert upon each other
