A transverse sinusoidal wave is generated at one end of a long horizontal string by a bar that moves with an amplitude of 1.12 cm . The motion of the bar is continuous and is repeated regularly 120 times per second. The string has linear density of 117g/m. The other end of the string is attached to a mass 4.68 kg. The string passes over a smooth pulley and the mass attached to the other end of the string hangs freely under gravity.
The maximum magnitude of the transverse component of tension in the string is

Options

A. zero
B. 3.77 N
C. 37.7N
D. 377 N
