Question

Two masses of 5kg and 10kg are connected to a pulley as shown. What will be the acceleration of the system $( g =$ acceleration due to gravity)

• A. $g$
• B. $\frac { g } { 2 }$
• C. $\frac { g } { 3 }$
• D. $\frac { g } { 4 }$

Answer 1

Answer: (C)

$\frac { g } { 3 }$

Answer 2

$a = \frac { m _ { 2 } - m _ { 1 } } { m _ { 1 } + m _ { 2 } } g = \frac { 10 - 5 } { 10 + 5 } g = \frac { g } { 3 }$
