Use Newton's Second Law: F = ma. You should be able to solve this problem really quickly.

i tried it but did not get the right answer. do we add all the forces up?

I'm not sure what your notation indicates -- I am assuming the letters in the brackets indicate the direction? Try drawing a free-body diagram first and remember to include an axis, something like this:|dw:1339815053559:dw|
