Type: MCQ-numerical-Medium-Class 11

A bob is whirled in a horizontal plane by means of a string with an initial speed of ω\omega rpm. The tension in the string is T. If speed becomes 2 ω\omega while keeping the same radius, the tension in the string becomes:

A

T4\frac{T}{4}

B

2T\sqrt{2}T

C

T
