Step-by-step explanation:

Given A 10 kg ball attached at the end of a rigid mass less rod of length 1 m rotates at constant speed in a horizontal circle of radius 0.5 m and period  of 1.58 s as shown in the figure. The force exerted by the rod on the ball  is

  • Now there is a ball and it is moving in the horizontal direction. Now we need to find the force exerted by the rod on the ball.  
  • Now there is a downward force on the ball and the ball has a tendency to fall. But there is a support from the rod.
  • Mass = 10 kg
  • So we have F1 = mg
  •                          = 10 x 10
  •                          = 100 N
  • Velocity = circumference / time period
  •                  = 2π r / T
  •                  = 2 x π x 0.5 / 1.58
  •                  = 1.98
  •                  = 2 m/s
  • So F2 = mv^2 / r
  •          = 10 x 2 x 2 / 0.5
  •         = 80 N
  • Now net force will be
  • Force = √F1^2 + F2^2
  •     = √(100)^2 + (80)^2
  •      = √16400
  •      = 128 N
