The deflection plates in an oscilloscope are 10 cm by 2 cm with a gap distance of 1 mm. a 100 volt potential difference is suddenly applied to the initially uncharged plates through a 1000 ohm resistor in series with the deflection plates. how long does it take for the potential difference between the deflection plates to reach 65 volts?
