An Electron Is Released from Rest at the Negative Plate

question 12

Short Answer

An electron is released from rest at the negative plate of a parallel plate capacitor.If the distance between the plates is 5 mm and the potential difference across the plates is 5 V,with what velocity does the electron hit the positive plate? (m_e = 9.1 *10 ^{- 31} kg,q_e = 1.6*10 ^{- 19} C. )
