One end of a string of length \( 1.0 \mathrm{~m} \) is tied to a body
\( \mathrm{P} \)
of mass \( 0.5 \mathrm{~kg} \). It is whirled in a vertical circle with angular frequency \( 4 \mathrm{rad} \mathrm{s}^{-1} \). Find the tension \( (T) \) in the string when the body is at the lowermost point of its motion. (Given \( g=10 \mathrm{~ms}^{-2} \) )
(1) \( 13 \mathrm{~N} \)
(2) \( 15 \mathrm{~N} \)
(3) \( 17 \mathrm{~N} \)
(4) \( 11 \mathrm{~N} \)
