Question

a ball of 3cm in diameter and 300g in weight is attached to the end of the string of 46cm in length. if it is rotated uniformly in a horizontal circle at the rate of 15rps what is the tension in the string​

Answer 1

Answer:

Radius of the circle =0.2 m

Angular frequency =n=6rpm

w=

60 s

6×2π

w=

5

π

=0.6284 rad/s

Linear velocity of the ball =rw

v=0.2 m×0.628 m/s

v=0.1257 m/s
