A 2 m ladder leans against a vertical wall. If the top of the ladder begins to slide down the wall at the rate 25cm//sec., then the rate ("in cm"//"sec".) at which the bottom of the ladder slides away from the wall on the horizontal ground when the top of the ladder is 1 m above the ground is :

A 22 m long ladder (whose foot is on the ground) leans against a wall making an angle of 60^(@) with the wall. What is the height (in m) of the point where the ladder touches the wall from the ground?

A ladder 5m long rests against a vertical wall. If its top slides down at the rate of 10 cm //sec , then, when the foot of the ladder is 4 m away from the wall, the angle between the floor and the ladder is decreasing at the rate of

A ladder 20 m long is placed against a wall so that the foot of the ladder is 10 m from the wall. The angle of inclination of the ladder to the horizontal will be :

A 2 m ladder leans against a vertical wall. If the top of the ladder begins to slide down the wall at the rate 25 cm/s, then the rate (in cm/s) at which the bottom of the ladder slides away from the wall on the horizontal ground when the top of the ladder is 1 m above the ground is

A ladder 10 meter long is leaning against a vertical wall. If the bottom of the ladder is pulled horizontally away from the wall at the rate of 1.2 meters per seconds, find how fast the top of the ladder is sliding down the wall when the bottom is 6 meters away from the wall

A ladder rests against a wall making an angle alpha with the horizontal. The foot of the ladder is pulled away from the wall through a distance ‘a’ so that it slides a distance ‘b’ down the wall making an angle beta with the horizontal then the value of (a)/(b) is

A ladder leaning against a window of a house makes an angle of 60^(@) with the ground. Ifthe distance of the foot of the ladder from the wall is 4.2 m, then the height of the point, where the ladder touches the window from the ground is Closest to:
