Two stones are projectd simu ltaneously ...

Two stones are projectd simu ltaneously with equal speeds from a point on an inclined plane along the line of its greatest slope upwards and downwards respectively. The maximum distance between their points of striking the plane is double that of when they are projected on a horizontal ground with saem speed. if one strikes the plane after two seconds of the other, then:

A

the angle of inclination of plnae is `45^(@)`

B

the speeds of their projection is `12.8m//s`

C

the angle of inclination of plnae is `60^(@)`

D

the speeds of their projection is 128 m/s
