Match the units and the quantity they measure Force A. volt Charge B. newton Current C. ampere Electric field D. coulomb Electric potential E. newton/coulombThe electric field a distance / from a positive point charge @ is A vector pointing away from the charge with magnitude k0/r-2 O A scalar constant along curved lines around the charge. O A vector pointing away from the charge with magnitude kQ /r A vector pointing toward the charge with magnitude KO/r-A charge is brought up next to a big metal plate. The electric eld near the plate is Q inclined at an angle tn the plate that depends en how far the paint on the plate is from the charge 0 Parallel to the plate 0 Perpendicular to the plate 0 Zero A proton close to Earth's surface will fall toward the center of Earth, accelerating at 9.8 m/s under Earth's gravitational field. If the proton has a positive charge of 1.6X 10-19 C, what size electric field would you need to counter this acceleration? The mass of the proton is 1.67 x 10-27 kg. 0 9.8 m/s2 O 10-7 N/C O 107 C/N 0 1.6x 10-26 N
