A particle with specific charge `q//m` moves rectilinerarly due to an electric field `E = E_(0) - ax`, where `a` is a positive constant, `x` is the distance from the point where the particle was initially at rest. Find:
(a) the distance covered by the particle till the moment it came to a standstill,
(b) the acceleration of the particle at that moment.

A particle of charge q and mass m moves along the x-axis under the action of an electric field E=k-cx , where 'c' is a positive constant and x is the distance from the point, where the particle was initially at rest. Calculate: (a) distance travelled by the particle before it comes to rest. (b) acceleration at the moment, when it comes to rest.

A particle of charge q and mass m moves rectilinearly under the action of an electric field E= alpha- beta x . Here, alpha and beta are positive constants and x is the distance from the point where the particle was initially at rest. Then: (1) the motion of the particle is oscillatory with amplitude (alpha)/(beta) (2) the mean position of the particles is at x= (alpha)/(beta) (3) the maximum acceleration of the particle is (q alpha)/(m) (4) All 1, 2 and 3
