The velocity of a wave along a plucked string is given by v=square root (TL/M). Where T is the tension in the string, L is the length and M is the mass. Show that the formula is dimensionally valid.

Answer:
we know that unit of velocity=meter/sec.
Given √TL/M
where ,T= force= mass*gravity=kg*m/sec2
L= meter
M= kg
>√kg*m/sec2*m/kg
> √m2/sec2
>. square root gets cancelled
> meter/sec
so L.H.S= R.H.S
