Question

Find,

Tension, acceleration​

Answer 1

Answer:

WE KNOW,

g = 10

in case of ➾

F.B.D

Using formula:-

$\boxed{ \green{T - g = Fnet}}$

$\red {\sf{ \underline{ solution : - }}}$

• Case of [A] Box ➝

=> Ｔ-１０ｍ = ｍａ.............(１)

• Case of [B] Box ➝

=> Ｔ -２０ｍ = ２ｍａ…………(２)

In Equation (１) and (２) ➦

=> Ｔ -１０ｍ +Ｔ-２０ｍ = ｍａ+ ２ｍａ

=> １０ｍ =３ｍａ

=> １０ｍ/３ｍ = ａ

=> １０/３ = ａ

Acceleration = 10/3

__________

Puting "a" value in Equation (１) ➠

• Ｔ-１０ｍ = ｍａ

=> Ｔ - １０ｍ = ｍ ×１０/３

=> Ｔ - １０ ｍ = １０ｍ/３

=> Ｔ = １０ｍ +３０ｍ/ ３

=> Ｔ =４０ｍ/３

Tension = 40m/3

You also write ➛

• Acceleration = 3.33

• Tension = 10.33 m
