Q.An electron is constrained to move along the x-axis enters a region of uniform electric field between two parallel plates with a velocity $u$ . The maximum distance it can travel in the region is (JEE Main 2020)

mu^2/(2eE)

mu^2/(eE)

2mu^2/(eE)

mu^2/(4eE)

The correct solution involves applying the fundamental concept to derive the final value step by step...
