A student taking a quiz finds on a reference sheet the two equations \( v=1 / T \) and \( v=\sqrt{T / \mu} \)
\( (\mu= \) mass/length, torque \( =r \times F \) and rest of symbols have usual notations.)
He has forgotten what \( T \) represents in each equation. Use dimensional analysis to determine the units required for \( T \) - in each equation.
(a) In first equation \( T \) represents tension.
(b) In first equation \( T \) represents time.
(c) In second equation \( T \) represents torque.
(d) In second equation \( T \) represents tension.
