In 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
  $10 \,revolution \,s^{-1}$
