(a)

Calculate the tension (in N) in a vertical strand of spiderweb if a spider of mass7.0010^-5kghangs motionless on it.

N

(b)

Calculate the tension (in N) in a horizontal strand of spiderweb if the same spider sits motionless in the middle of it much like the tightrope walker in the figure.

The strand sags at an angle of13.0below the horizontal.

N

Compare this with the tension in the vertical strand (find their ratio).
