Hi I just wanted to verify my process for solving this question:
Ok, first of all, I made a diagram to visualize the forces working on the sphere.
To get the Force magnitude of the wind (Fw), I started with the weight of the sphere ( 2.94x10^(-3) N ) and since the sphere is in equlibrium, then the vector Tj is the same as the weight.
Then I used the trig relation Tan(37) = Tj/Ti, solved for Ti and again since it's in equlibrium in the i (x) axis, Ti = (Fw)
For the tension of the cord, I simply used T = (T Cos(37))i
Did I managed to do it correctly or did I completely veered off? Also, did I used the correct vector notation?
4. A sphere of mass 3.0 x 10-4 kg is suspended from a cord. A steady horizontal breeze pushes the sphere so that the cord makes an angle of 37° with the vertical when at rest. Find (a) the magnitude of that push and (b) the tension in the cord.
