A particle of mass m and charge `-q` is projected from the origin with a horizontal speed v into an electric field of intensity E directed downward. Choose the wrong statement. Neglect gravity

Options

A. The kinetic energy after a displacement y is qEy
B. The horizontal and vertical components of acceleration are `a_(x)= qE//m, a_(y)= 0 `
C. The equation of trajectory is `y^(2)=(1)/(2)((qEx^(2))/(mv^(2)))`
D. The horizontal and vertical displacements x and y after a time t are `x=vt^(2)` and `y=(1)/(2)a_(y)t^(2)`
