CENTRIFUGAL FORCE

Consider the following two statements A and B and identify the correct choice in the given choices (A) Centripetal force, centrifugal force are equal in magnitude and opposite in direction but they are not force of action and force of reaction respectively because both act on same body. (B) Centrifugal force is a pseudo force in both inertial frame of reference and non inertial frame of reference.

Water flows along a horizontal pipe with a curve having a radius of R=20 m. Find the lateral pressure of the water caused by the centrifugal force. The pipe diameter d = 20 cm, and m = 300 tons of water pass through the pipe in t = 2 hours.

Two identical balls 1 and 2 are tied to two strings as shown in figure. They are rotated about point O. Ball 1 is observed from ball 2, centrifugal force on ball 1 is F_(1) . Similarly, ball 2 is observed from ball 1 and centrifugal force on ball 2 is F_(2) , then

Calculate the ratios of the following accelerations: the acceleration w_1 due to the gravitational force on the Earth's surface, the acceleration w_2 due to the centrifugal force of inertia on the Earth's equator, and the acceleration w_3 caused by the Sun to the bodies on the Earth.

When a conducting disc is made to rotate about its axis, the centrifugal force causes the free electrons to be pushed toward the edge. This causes a sort of polarization and an electric field is induced. The radial movement of free electrons stops when electric force on an electron balance the centrifugal force. Calculate the potential difference developed across the centre and the edge of a disc of radius R rotating with angular speed omega . [This potential difference is sometimes called as sedimentation potential]. Take mass and charge of an electron to be m and e respectively

Cell fractionation involves I. homogenisation of cell constituents. II. Subjecting the homogenate to centrifugal force. III. Detection of slight variation of amino acids. IV. Staining of structures of living cells.
