Question

In the following figure, the pulley is massless and frictionless. The relation between $T _ { 1 }$ , $T _ { 2 }$ and $T _ { 3 }$ will be

• A. $T _ { 1 } = T _ { 2 } \neq T _ { 3 }$
• B. $T _ { 1 } \neq T _ { 2 } = T _ { 3 }$
• C. $T _ { 1 } \neq T _ { 2 } \neq T _ { 3 }$
• D. $T _ { 1 } = T _ { 2 } = T _ { 3 }$

Answer 1

Answer: (D)

$T _ { 1 } = T _ { 2 } = T _ { 3 }$

Answer 2

Since through a single string whole system is attached so $W _ { 2 } = T _ { 3 } = T _ { 2 } = T _ { 1 }$
