A) 20 N
B) 40 N
C) 10N
D) 32 N
Correct Answer: D
Solution :
Acceleration of the system \[a=\frac{{{T}_{3}}}{{{m}_{1}}+{{m}_{2}}+{{m}_{3}}}\] \[=\frac{40}{10+6+4}=2m/{{s}^{2}}\] Tension in the string \[{{T}_{2}}=({{m}_{1}}+{{m}_{2}})a\] \[=(10+6)\times 2\] \[=32N\]You need to login to perform this action.
