Q1:

A point charge creates an electric field in the region of space around it. What information must be known in order to determine the magnitude and direction of the electric field at a given point in space? Check all that apply. :] Electric potential 3 Distance away from the charge 3 Mass of the charge 3 Sign of the charge :] Magnitude of the charge A parallel plate capacitor is made out of two plates, each 1.0 m2 that are 0.02 m apart. The voltage between the plates is 1000 V. Which change will double the electric field between the plates? 0 Bring the plates so that they are 0.01 m apart. 0 None of the changes will double the electric field 0 Increase the voltage across the plates to 1500 V 0 Make both plates 2.0 m2 0 Separate the plates to 0.04 m
