Question 34: NCERT Class 12th Physics: Chapter 1 – Electric Charges And Fields
Suppose that the particle in question 33 is an electron projected with velocity vx = 2.0 × 106 m s-1. If E between the plates separated by 0.5 cm is 9.1 × 102 N C-1 where will the electron strike the upper plate? (|e| = 1.6 × 10-19, me = 9.1 × 10-31 kg)
Solution:
If the electron is released just near the negatively charged plate, then y = 0.5 cm and hence
