Question 14. Two oppositely charged parallel plates have an electric potential difference of 1.2 x 10² V across them. The plates are 4.5 x 102 m apart. An alpha particle enters the region between the plates through a hole in the negatively charged plate and comes to rest just before it reaches the positively charged plate. Positively charged plate Negatively charged plate Path of alpha particle Determine the initial speed of the alpha particle as it enters in between the parallel plates.
