In an arrangement shown in figure all surfaces are smooth and strings and pulkeys are massless. Given m1= 1kg, m2= 2kg, m3=4kg and g=10 , find the acceleration of all the blocks and tension in the two string |
|
Answer» Explanation:f net =mxa so here the external force is tension t=malet the string connected in b/w M2 and M3 is t' and the m1 and pulley is TSO the EQUATIONS are m3,40-t'=4a'm2,t'-2t =2am1,t=a by solving we get a+a'=10 =>a=10-a' by further solving we will get ACCELERATION |
