From your Physics textbook or from the Internet, you can learn that for an elastic string, velocity of the transverse wave is
v =
,
where "T" is tension of the string (in Newtons, N) and "d" is the linear density of the string (in kilograms per meter, kg/m).
In this formula, the velocity "v" of the transverse wave is in meters per second, m/s.
By substituting the given input values, you get
193 =
.
Square both sides and express T =
to get the value of T equal to 85.67 Newtons.
Answer. The tension of the string is 85.67 Newtons.
Solved.
