Q. A pallet of mass 1 g is moving with an angular velocity of 1 $rad{s\ }^{- 1}$ along a circle of radius 1 m the centrifugal force is
A) 0.1 dyne
B) 12 dyne
C) 10 dyne
D) 100 dyne
Explanation
(d) $Given,\ m = 1 \times 10^{- 3}\ kg,\ \omega = 1\ rad\ s^{- 1}\ and\ r = 1m$
Hence, centrifugal force $= m\omega^{2}r = 10^{- 3}N$
$1N = 10^{5}\ dyne$
$\therefore Centrifugal\ force = 100\ dyne$
