A transverse wave travels on a steel wire with a velocity
when tension in it is
. When the tension is changed to
, the velocity changed to
. The value of
is close to
Text Solution
Verified by ExpertsThe correct answer is:
C
Speed of transverse wave over a string is given by
(i)
where,
tension in string
mass per unit length of string.
Here, when velocity is
, then tension, 
Let when velocity is
, then tension is
, hence from
Eq. (i), we get
