| Two bodies of mass 4 kg and 6 kg are tied to the ends of a massless string. The string passes over a pulley which is frictionless (see figure). The acceleration of the system in terms of acceleration due to gravity (g) is: [NEET 2020] |
 |
A) g/2
B) g/5
C) g/10
D) g
Correct Answer: B
Solution :
| [b] \[a=\frac{({{m}_{1}}-{{m}_{2}})g}{({{m}_{1}}+{{m}_{2}})}\] where \[{{m}_{1}}>{{m}_{2}}\] |
| \[a=\frac{(6-4)g}{6+4}\] |
| \[a=\frac{g}{5}\] |
| Note: Here no option is given according to acceleration of COM of the system. |
