A string (A) hanging from the ceiling has a 1 kg mass attached to it and hanging below this mass is string (B) with a 2 kg mass attached. Both of the strings are massless.
How do I calculate the tension in Cord B?
Schematically, it looks like this (turned 90 degrees)
The only mass string B is supporting is the 2kg mass. So the tension in string B is
=2kg * g
