Question

Two masses m1 and m2 are attached to a string which passes over a frictionless smooth pulley. When m1=10 kg, m2=6 kg, the acceleration of masses is (A) 20 m / s2 (B) 2.5 m / s2 (C) 5 m / s2 (D) 10 m / s2

Acceleration of the system,br/> a=(m1-m2/m1+m2) g=(10-6/10+6) × g=2.5 m / s 2

Q. Two masses $m_{1}$ and $m_{2}$ are attached to a string which passes over a frictionless smooth pulley. When $m_{1} = 10 k g$ , $m_{2} = 6 k g$ , the acceleration of masses is

$20 m / s^{2}$

$2.5 m / s^{2}$

$5 m / s^{2}$

$10 m / s^{2}$

Acceleration of the system,br/> $a = \frac{m _{1} - m _{2}}{m _{1} + m _{2}} g = \frac{10 - 6}{10 + 6} \times$
$g = 2.5 m / s^{2}$
