Answer 1

Answer 2

When the bodies are released, the acceleration of the masses is​ 2.45m/s².

Let the tension in the string be  T N

For the heavier mass 10kg, its weight is 10kgf.

Let acceleration of the mass be 'a' m/s²

Difference between Tension and Weight of the body = Mass×Acc.

So, 10g-T = 10a    

⇒T = 10g - 10a       ...(1)

where g is the acceleration due to gravity

For the lighter mass 6kg, its weight is 6kgf.

Difference between Tension and Weight of the body = Mass×Acc.

So, T-6g = 6a         ...(2)

Substituting the value of T from (1) in (2),

10g-10a -6g = 6a

⇒4g = 16a

⇒a = g/4

where g = 9.8m/s²

So, a = 9.8/4 = 2.45m/s²
