Question

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 1

Answer:

Explanation:

f net =mxa

so here the external force is tension

t=ma

let the string connected in b/w m2 and m3 is t' and the m1 and pulley is t

so the equations are m3,40-t'=4a'

m2,t'-2t =2a

m1,t=a

by solving we get a+a'=10

=>a=10-a' by further solving we will get acceleration
