In an experiment you find that a small styrofoam ball of mass m -2.60x10 kg can be suspended in mid-air, held up against the force of gravity, by an electric field of magnitude 2.36x10¹ N/C pointing straight downward, towards the earth. What is the charge on the styrofoam ball? Give your answer in nanoCoulombs (10° C) to at least three significant digits. So, for example, if the charge is 1.55x10* C you should enter as your answer 1.55. If the charge is -7.89x107 C you should enter as your answer-789 The field caused by charges in semiconductor devices can be an important factor in the operation of the device. Consider a situation where there are two line charges, one positive and one negative, as shown in the figure. The magnitude of the charge on each line is Q-21x1017 C (equal to the charge of around 100 electrons), the length of the rods is L-6.6-4x10 m. The distance between the charged lines is d-8.90x107 m. What is the magnitude of the electric field caused by these two charged rods at a point half-way between the centers of the lines? Give your answer in N/C to at least three significant figures. Note: Do not try to use scientific notation (such as 5.64x10).
