A particle of mass m and charge q is projected in a region where an electric field by  $\overrightarrow{E}=E_0\widehat{i}$ exists, with velocity $v_0\widehat{j}$ from the origin at time t=0, then choose the correct statements (Assuming $m^2{v}_0^2=2q{E}_{0}m{x}_0$).

Radius of curvature of the particle when its x-coordinate becomes $x_0$ is $2x_0$

Speed of the particle when its x-coordinate becomes $x_0$ is  $2v_0$

Speed of the particle when its x-coordinate becomes $x_0$ is $\sqrt{2}{v}_0$

Radius of curvature of the particle when its x-coordinate becomes $x_0$ is $4\sqrt{2}{x}_0$
