Two bodies of mass 6kg and 4kg are tied to a string as shown in the adjoining figure. If the table is smooth and pulley frictionless, then acceleration of mass 6kg will be (g = 10 m s- 2): <img class="img-fluid question-image" alt="Question" src="https://cdn.tardigrade.in/q/nta/p-7kwyclgrfuy1jta2.jpg" /> (A) 60ms- 2 (B) 40ms- 2 (C) 6ms- 2 (D) 4ms- 2

6g-T=6a...(1) T=4a...(2) ∴ 6g=(.6+4.)a or a=(6 g/10)=(6 × 10/10)=6ms- 2

Q. Two bodies of mass $6 k g$ and $4 k g$ are tied to a string as shown in the adjoining figure. If the table is smooth and pulley frictionless, then acceleration of mass $6 k g$ will be $(g = 10 m s^{- 2}) :$

$60 m s^{- 2}$

$40 m s^{- 2}$

$6 m s^{- 2}$

$4 m s^{- 2}$

$6 g - T = 6 a ... (1)$
$T = 4 a ... (2)$
$∴ 6 g = (6 + 4) a$ or $a = \frac{6 g}{10} = \frac{6 \times 10}{10} = 6 m s^{- 2}$
