Tension Problem! Help please!
I have a question that relates to a vertical/horizontal pulley system:
i'll try drawing the diagram, hopefully someone can understand!
O2.0kg





mass=5.0Kg
alright, i guess i should explain that ^^^ if it clarifies the diagram a bit. alright, so there's a mass of 2.0kg on a surface attached to a string which attaches to a pulley (shown by "O") on the edge of the surface. This string is also connected to a 5.0kg mass which is shown in the diagram to simply be hanging off the pulley.
So the question is: A 2.0kg mass, placed on a smooth level table, is attached by a light string passing over the edge of a table. Determine the tension in the string. (the answer given is 14N)
i've found that the total mass of the two are 7.0kg, and is aware that the tension is the same on both the strings. however, what formula would i use to execute this question. would multiplying each mass by 9.81 assist? if the diagram is difficult to understand, please respond so i can further clarify it!
ps) if anyone knows how to add in diagrams, etc. other than using keyboard letters and symbols, that would be great!
