A spider begins to spin a web by first hanging from a ceiling by his fine, silk fiber. He has a mass of 0.025 kg and a charge of 2.6 C. A second spider with a charge of 4.2 C rests in her own web exactly 1.6 m vertically below the first spider. (a) What is the magnitude of the electric field due to the charge on the second spider at the position of the first spider? 466.6 How does electric field relate to charge? N/C (b) What is the tension in the silk fiber above the first spider? 1.09e-11 X How does the electric field relate to the force? How do you calculate the net force? N
