Question1

One end of a horizontal string of linear density 6.9×10-4 is attached to a small-amplitude mechanical 150- oscillator. String passes over a pulley, a distance away, and weights are hung from this end. What mass should be hung from this end of string to produce one loop of a standing wave? Imagine string at the oscillator is a node, which is almost true.

Question2

A fishing pole is 2.00 m long inclined to the horizontal at an angle of 20.0 degree what is torque exerted by the fish about an axis perpendicular to the page and passing through the hand of the person holding pole?
