4 questions:
1). A 5 cm spring is suspended with a mass of 2.417 g attachedto it which extends the spring by 2.409 cm. The same spring isplaced on a frictionless flat surface and charged beads areattached to each end of the spring. With the charged beads attachedto the spring, the spring's extension is 0.259 cm. What are thecharges of the beads?
2). Two equally charged, 1.862 g spheres are placed with 3.188cm between their centers. When released, each begins to accelerateat 261.446 m/s2. What is the magnitude of the charge oneach sphere? Express your answer in microCoulombs.
3).A +3 nC charge is located at (0,11.90) cm and a -8nC chargeis located (3.38, 0) cm.Where would a -8 nC charge need to belocated in order that the electric field at the origin be zero?Find the distance r from the origin of the third charge.
