Question

A string of length 1 m is fixed at one end and carries a mass of 100 g at the other end. The string makes (2/TT) revolutions per second around vertical axis through the fixed end. What is the tension in the string ​

Answer 1

Answer:

w=

π

2

rev. per sec ⟹w=2πν=4

From figure R=Lsinθ

∴ Tsinθ=MRw

2

⟹ T=MLw

2

=ML(4)

2

=16ML
