Question

Water is flow at rate of 5m3< sup> /min into a conical vassal whose semi vertical angle is tan-1 ((1/2))Then there rate of change in height of water level. When height of water level is 10 m is (A) (1/2π) m/min (B) (1/4π) m/min (C) (1/5π) m/min (D) (1/6π) m/min

Tardigrade Admin · Accepted Answer

Correct answer is (c) (1/5π) m/min

Q. Water is flow at rate of 5m^{3<\sup> /min into a conical vassal whose semi vertical angle is tan $^{- 1} (\frac{1}{2})$ Then there rate of change in height of water level. When height of water level is 10 m is}

$\frac{1}{2 π} m / min$

$\frac{1}{4 π} m / min$

$\frac{1}{5 π} m / min$

$\frac{1}{6 π} m / min$

Correct answer is (c) $\frac{1}{5 π} m / min$
