17. Not a vector - Distance 18 Three equal positive charges of 41 st at coloumb each are located at the vertices of an equiangular triangle of 31 cm leg. What is the magnitude of the force experience by each charges due to each charges?F= dynes 19. Two metallic plates seperated by 9.8 cm. If a plastic material is inserted between the plates of the capacitor completely filling the space, the capacitance becomes 7 times the original. Determine the dielectric constant the plastic material 20. Acpacitor has 0.095x0.095 m parallel plates. The distance between the plates is 0.042 m in free air. A dielectric material whose permitivity is 6 and 0.008 m thick is placed in the upper plate, leaving an air gap between the bottom plate dielectric, what is the capacitance of the capacitor? C=pF
