Class 11Physics2 Motion in a PlaneNon-uniform Circular Motion (Centrifugal/Centripetal and tangential Accelaration)
EasyIn a hypothetical ring-shaped satellite rotating in space, artificial gravity can be achieved using centripetal force. If the satellite has a radius of $10 \,m$, then to achieve a centripetal acceleration at a point on the circumference of $10 \,ms^{-2}$, its angular speed is:
- A$1 \,rad \,s^{-1}$
- B$10 \,rad \,s^{-1}$
- C$1 \,revolution \,s^{-1}$
- D$10 \,revolution \,s^{-1}$
