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
