A stair-case of length l rests against a vertical wall and a floor of a room. Let P be a point onthe stair-case, nearer to its end on the wall, that divides its length in the ratio 1: 2. If the staircase begins to slide on the floor, then the locus of Pis:

A stick of length l rests againsts the floor and a wall of a room. If the stick begins to slide on the floor, then the locus of its middle point is

A stick of length I rests against the floor and a wall of a room. If the stick begins to slide on the floor, then the locus of its middle point is

A stick of length 10 units rests against the floor and a wall of a room. If the stick begins to slide ontfloor then the locus of its middle point is:

A stick of length 10 units rests against the floor and a wall of a room.If the stick begins to slide ontfloor then the locus of its middle point is:

A stick of length 10 units rests against the floor and a wall of a room. If the stick begins to slide ontfloor then the locus of its middle point is:

A stick of length 100cm rests against a vertical walland the horizontal floor.If the foot of the stick slides with the constant velocity of 10cm/s then find the magnitude of the velocity of the middle point of the stick when it is inclined at with the floor.

A stick of length a cm rests against a vertical wall and the horizontal floor.If the foot of thes tick slides with a constant velocity of b cm/s,then the magnitude of the velocity of the middle point of the stick when it is equally inclined with the floor and the wall,is

A rod of AB of length 3 rests on a wall as follows : P is a point on AB such that AP : PB = 1 : 2 If the rod slides along the wall, then the locus of P lies on
