Answer:
hear is the answer
Explanation:
40/3 kg
mass of blocks are 10 Kg and 20 Kg respectively.
Write the equation of motion in terms of T and a.
Where, T is tension and a is acceleration,
T - 10g = 10a ............(I)
20g - T = 20a ............(II)
add (I)+(II)
a = g/3 meter/sec^2
See the attachment,
put the value of a in (i),
T = 40g/3 N
Spring reading T/g = 40/3 Kg.
