The figure shows four pairs of parallel identical conducting plates, separated by the same distance 2.0 cm and arranged perpendicular to x-axis. The electric potential of each plate is mentioned. The electric field between a pair of plates is uniform and normal to the plates.
An electron is projected from the right plate of set I directly towards its left plate. It just comes to rest at the plate. The speed with which it was projected is about:
\(\left(\right.\) Take \(\left.({e} / {m})=1.76 \times 10^{11} {C} / {kg}\right)\)
- 1.3 \(\times\) 105 m/s
- 2.6 \(\times\) 106 m/s
- 6.5 \(\times\) 105 m/s
- 5.2 \(\times\) 107 m/s
Answer
(B) 2.6 10 6 m/s
