A 1.50 m string is tensioned between 2 points and has a linear mass density of 5.10 10-4 kg / m. Waves with a frequency of 410. Hz are sent through the string, resulting in a standing wave pattern in which the ends coincide exactly with a knot and there are 4. bellies between both points. How great is the tension in the string? Select the correct answer from the following list:

 

.539e-4 N 48.2 N .894e-2 N 772. N
