A wheel of diameter 20 cm is rotating at 600 rpm. The linear velocity of particle at its rim is
6.28 cm/s
62.8 cm/s
0.628 cm/s
628.4 cm/s
Explanation:
Radius = 10 cm = 0.1 metre
Angular velocity = 600 revolution per minute = 600*2π/60
radian/second = 20π rad / sec
Linear velocity of the point at rim = Radius*Angular velocity = 0.1*20π = 2π metres/second
= 6.28 m/s
