3a) 3b) A uniform sheet of charge lies on a horizontal surface. A point charge of -8 micro-coulombs is located 0.2 meters below the sheet. At a point 0.45 meters above the sheet, directly above the charge, the total electric field from the sheet and the point charge is zero. Then, the point charge below the sheet is removed and a point charge of -8 micro- coulombs with a mass of 0.2 kg is placed 0.45 meters above the sheet and launched vertically upwards at 14 m/s. What is the maximum height the charge reaches (maximum distance from the sheet) in meters when including the weight as well? A negative charge with a mass of 0.6 kg is placed on a string which is placed between a capacitor which is orientated vertically as shown. The charge swings to an angle of 14.2 degrees with the vertical before coming to equilibrium. Then, a positlve charge with a magnitude twice as large as the first charge replaces the charge on the string and the same capacitor is changed to orientated horizontally as shown. What is the tension in the string in this second scenario in Newtons? 2 pesative negative sheet nnesheet Ром.ive sheet
