A square coil `ACDE` with its plane vertically is released from rest in a horizontal uniform magnetic field `vec(B)` of length `2L` . The accelaration of the coilis

less than `g` for all the time till the loop crosses the magnetic field completely

less than `g` when it enters the field and greater than `g` when it comes out of the field

`g` all the time

less than `g` when it enters and comes out of the field but equal to `g` when it is within the field
