A particle of charge q and mass m moves rectillineary under the action of an electric field `E=alpha-betax` Here `alpha` and `beta` are positive constants ans x is the distance from the point where the partical was initially at rest. Then

Options

A. The motion of the particle is oscillatory
B. The amplitude of the particle is `(alpha/beta)`
C. The mean position of the particle is at `x=(alpha/beta)`
D. The maximum acceleration of the particle is `(qalpha)/m`

Answer

A, B, C, D
