Centripetal and Centrifugal Force

Centripetal and centrifugal xylems are important features of (a) Root and stem, respectively (b) Exarch and endarch, respectively (c) Endarch and exarch, respectively (d) Both a and b

Centrifugal force is:

Distinguish between Centrifugal and centripetal forces. Give examples.

Assertion: The centripetal forces and centrifugal forces never cancel out. Reason: They do not act at the same time.

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

Assertion If a particle is rotating in a circle, then centrifugal force is acting on the particle in radially outward direction . Reason centrifugal force is equal and opposite to the centripetel force.

Can you recall, what centrifugal force is, and think why a molecule with higher mass/density would sediment faster?

A particle of mass m is moving in a circle of radius (r) with changing speed (v) the direction of centripetal force and tangential force are shown below the value of alpha is

A gramophone disc rotates at 60 rpm . A coin of mass 18 g is placed at a distance of 8 cm from the centre . Calculate centrifugal force on the coin . Take pi^(2) = 9. 87 .

Assertion: Electrons in the atom are held due to coulomb forces. Reason: The atom is stable only because the centripetal force due to Coulomb's law is balanced by the centrifugal force.
