A ladder is resting with a vertical wall at an angle of `30^(@)`. If a man is ascending the ladder of at the rate of 6 feet/sec, then the rate at which the man is approaching the wall, is

A ladder is resting with the wall at an angle of 30^circ . A man is ascending the ladder at the rate of 3 ft/sec. His rate of approaching the wall is

A ladder is resting with the wall at an angle of 30^circ . A man is ascending the ladder at the rate of 3 ft/sec. His rate of approaching the wall is

A ladder is inclined to a wall making an angle of 30 with it.A man is ascending the ladder at the rate of 3m/sec. How fast is he approaching the wall?

A ladder is inclined to a wall making an angle of 30° with it. A man is ascending the ladder at the rate of 3 m/sec. How fast is he approaching the wall ?

A ladder, metres long standing on a floor leans against a vertical wall . If the top of the ladder slides downwards at the rate of 10 cm/sec , then the rate at which the angel between the floor and the ladder is decreasing when the lower end of the ladder is 2 metres away from the wall is

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 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 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 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 ladder, 5 meter long, standing on a horizontal floor, leans against a vertical wall. If the top of the ladder slides downwards at the rate of 10 cm/sec, then the rate at which the angle between the floor and the ladder is decreasing when lower end of ladder is 2 metres from the wall is ............
