Question

What angular velocity in revolution per second is needed for a centrifuge to produce an centripetal acceleration of a=9800m/s square at radius 10 cm.

Answer 1

Option (d) is correct.

Step-by-step explanation:

centripetal acceleration = a = r ω²

r= radius= 10 cm= 0.1 m

ω= angular velocity

9800= (0.1) ω²

ω=313 rad/sec

ω= 313 rad/s * (1 rev/2π rad)

ω=49.8 rev/s
