Consider a pyramid OPQRS located in the first octant (xge0, yge0, zge0) with O as origin and OP and OR along the X-axis and the Y-axis , respectively. The base OPQRS of the pyramid is a square with OP=3. The point S is directly above the mid point T of diagonal OQ such that TS=3. Then,

Answer»

<P>the acute angle between OQ and OS is `(pi)/(3)`
the EQUATION of the plane containing ht `triangleOQS` is x-y=0
the length of perpendicular from P to the plane containing the `triangleOQS` is `(2)/(SQRT(3))`
the perpendicular distance from O to the straight line containing RS is `sqrt((15)/(2))`

Answer :`(b,c, d)`
