Question 4 1 pts Electric charge q=-3.7 mC and mass m=3.5X 10 kg moves with a speed v=8 km/s along the electric field (with it or against it). What is the speed of the charge after the charge travels through a potential difference AV=-8 kV. Express your answer in km/s, rounded to three places after the decimal. Question 5 1 pts A parallel plate capacitor is made of two metallic, circular plates of radius 4.38 cm separated by distance 0.62 mm and contains a glass plate with dielectric constant 5.5. The capacitor is connected to a battery that provides voltage 4.6 V. How much charge is stored on each plate of the capacitor? Provide your answer in nanocoulombs, with a precision of two places after the decimal
