the burden of the field is W = mg = 3 x 10^-4 kg * 9.8 m/s^2 = 2.ninety 4 x 10^-3 N At 37 tiers, the ingredient to pressure in the vertical route must be equivalent to the burden of the field, as there aren't the different forces in the vertical route. subsequently, Ty = 2.ninety 4 * 10^-3 N the pressure in the cord by using trigonometry (for the reason that Ty= T cos 37) is T = 3.sixty 8 x 10^-3 N The ingredient to pressure in the horizontal route is an identical because the rigidity using he wind on the field. Tx = T sin 37 = 2.22 x 10^-3 N
