a=[(m1 - m2/m1 + m2)]g=[(5 - 4.8/5 + 4.8)]× 9.8=0.2ms- 2

Q. Two masses $m_{1} = 5 k g$ and $m_{2} = 4.8 k g$ tied to a string are hanging over a light frictionless pulley. What is the acceleration of the masses when they are free to move $(g = 9.8 m s^{- 2})$

$0.2 m s^{- 2}$

$9.8 m s^{- 2}$

$5 m s^{- 2}$

$4.8 m s^{- 2}$

$a = [\frac{m _{1} - m _{2}}{m _{1} + m _{2}}] g = [\frac{5 - 4.8}{5 + 4.8}] \times 9.8 = 0.2 m s^{- 2}$

Q. Two masses m1​=5kg and m2​=4.8kg tied to a string are hanging over a light frictionless pulley. What is the acceleration of the masses when they are free to move (g=9.8ms−2)

0.2ms−2

9.8ms−2

5ms−2
