Question 4 1 pts Electric charge q=-5.6 mC and mass m=3.2>

Question 4 1 pts Electric charge q=-5.6 mC and mass 6 kg moves with a speed v=8 km/s in +x direction in the electric field of magnitude E=297 N/C that points in the -x direction. 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 3.84 cm separated by distance 0.56 mm and contains a glass plate with dielectric constant 5.9. The capacitor is connected to a battery that provides voltage 4.8 V. How much charge is stored on each plate of the capacitor? Provide your answer in nanofarads, with a precision of two places after the decimal.
