A coffee pot in the form of a circular cylinder of radius 2 in. is being filled with water flowing at a constant rate. If the water level is rising at the rate of 0.2 in./sec, what is the rate at which water is flowing into the coffee pot

The rate at which water flowing is 0.04116 liter per second

Explanation:

we know that the rate at which water is flowing into pot is equal to the amount of water flowing into pot per second .

⇒Volume of water entering per second =

area =

given that r=

⇒ This is equal to The rate at which water level is raising ×area of the given pot .

 ⇒0.2×2×2×π cubic inch per second

 ⇒2.515 cubic inch per second

we know that

 ≡0.04116 liter per second

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
