Question

a mass is supported on a frictionless horizontal surface if attached to a string and rotate about a fixed centre at an angular velocity Omega not. if length of the string and angular velocity are doubled the tension in the string which was initially T not is now

Answer 1

Answer :

8To

I have attached my explanation below

Answer 2

$8T_{0}$

Explanation:

Given that,

Angular velocity = ω∞

​ Tension in the string $T_{0}$ = mRω^2o

In the next situation where the length of the string and angular velocity doubled

T' = m × 2l × 4ω^2o

T = m(2l) (4ω^2o)

⇒ T = $8mR$ω^2o

∵ T = $8T_{0}$

Hence, option D is the correct answer.
