Find acceleration of block and tension in strings if m1 =8kg m2= 4kg and take g=10m/s²

= 8kg

= 4kg

g = 10m/s²

→Acceleration of block

→Tension in strings

Let, the two equation will be ,

8g - T = 8a ..... Equation no (1)

T - 4g = 4a ..... Equation no (2)

Putting the value of equation no (1) and (2) we get,

4g = 12a

4 × 10 = 12a

40 = 12a

a =

a =

Again, we have to putting the value of a in the equation no (2) we get,

T - 4g = 4 ×

T - 4 × 10 = 4 ×

T - 40 =

T = + 40

T =

T = N

Acceleration of block = m/s².

And, Tension in strings = N
