A particle of charge q and mass m is subjected to an electric field
E = E₀
(1 – x²) in the x-direction,
where and E₀
are constants. Initially the particle was at rest at x = 0. Other than the initial
position the kinetic energy of the particle becomes zero when the distance of the particle from the
origin is :
