mechanics 1 easy question watch

1. there are 5 spheres joined together by inextensible strings. the total air resistance acting upwards on the spheres is 0.5mg. i have to find the tension in each of the 4 strings when
a. the air resistance on each sphere is 1/10mg
b. when the air resistance on the uppermost sphere is 3/10mg and the air resistance on each of the 4 spheres is 1/20mg

i have been trying for ages i just cant work it out !!!!

thanks (any help will be grateful)
2. sorry the total air resistance piece isnt included in this question so ignore the 0.5mg

Is the top sphere fixed in position and are the spheres identical? It might help to draw a diagram, and post your thoughts
4. the spheres are identical. i have to go to lesson now so i will post a pic and my ideas later. thanks anyways xxx
