Homework Statement

A system with a pulley, string, and mass has a string on a pulley holding 0.5 kg on one end and 2.0 kg on the other. It is in static equilibrium; the pulley is frictionless; the string is massless.
What is the tension in the string holding the pulley?
What is the value of the normal force on the 2.0 kg box?

Homework Equations

hi runningirl!

…
t-(2*9.8)=F? (part a)

is the 2.0 kg mass resting on the ground?

if so, always start with the mass with the least number of forces acting on it (because that's easiest! ), and then work your way round to the others

in this case, that's the 0.5 kg mass …

so what is the ∑F = 0 equation for that? ​
