A block is kept on a smooth inclined plane of angle of inclination `30^(@)` that moves with a constant acceleration so that the block does not slide relative to the inclined plane. Let `F_(1)` be the the contact force between the block and the plane . Now the inclined plane stops and let `F_(2)` be the contact force between the two in this case. Then, `F_(1)//F_(2)` is

`1`

`(4)/(3)`

`2`
