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 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 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

A charged particle having charge q and mass m moves rectilinearly under the action of the electric field E(x)=(4-3x)N//C where x is the distance was initially at rest. The distance travelled by the particle till it comes instantaneously to rest again for the first time, is

A particle moves along a line by s = (t^(3))/(3) - 3t^(2) + 8t then the distance travelled by the particle before if first comes to rest is
