Answer:

Normal force

Step-by-step explanation:

  • The force is centipetral force

Calculating :-

  • Mass=m=20kg
  • Radius=r=4m
  • Velocity=10m/s=v

We know


\boxed{\sf F_c=(mv^2)/(r)}


\\ \sf\longmapsto F_c=(20(10)^2)/(4)


\\ \sf\longmapsto F_c=(20(100))/(4)


\\ \sf\longmapsto F_c=(2000)/(4)


\\ \sf\longmapsto F_c=500N
