Two particale of same mass and charge throw in same direction along the horizonal with same velocity v from two didffent heights `h_(1)` and `h_(2)` `(h_(1)lth_(2)).` Initially they were located in the same vertical line. Select the corredct alternative (s).

A

Both the particles always lie on a vertical line

B

Acceleration of the centre of mass of the two particles is g downwards

C

Horizontal dosplacement on reaching to ground of particle lying at `h_(1)` is less than the value, which would had been in the absence of charges on them

D

Horizontal displacement on reaching to ground of particle lying at `h_(2)` is more than the value, which would had been in the absence of charges on them
