A4 kg box is on a frictionless 35° slope and is connected via a massless string over a massless, frictionless pulley to a hanging 2 kg weight, (a) what is the tension in the string if the 4 kg box is held in place, so that it cannot move? (b) if the box is then released, which way will it move on the slope? (c) what is the tension in the string once the box begins to move?

![T=mgwhere m is mass, g is gravitational force taken as 9.81T=2*9.81 =19.62 N (b) Block mass of 4 Kg [tex]T'-mg sin \theta=0](/tpl/images/0339/1268/8aaa0.png)
hence 
where m is mass and g is gravitational force 
, then the box moves down the slope
