Centrifugal Force

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

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.

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.

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.

A particle of mass m rotates in a circle of radius a with uniform angular speed omega_(0) . It is viewed from a frame rotating about the z-axis with a uniform angualr speed omega . The centrifugal force on the particle is

A midpoint of a thin uniform rod AB of mass m and length l is rigidly fixed to a rotation axle OO^' as shown in figure. The rod is set into rotation with a constant angular velocity omega . Find the resultant moment of the centrifugal forces of inertia relative to the point C in the reference frame fixed to the axle OO^' and to the end.

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.
