A) \[\frac{P\,m}{M+m}\]
B) \[\frac{P\,m}{M-m}\]
C) P
D) \[\frac{P\,M}{M+m}\]
Correct Answer: D
Solution :
[d] Let acceleration of system (rope + block) is a along the direction of applied force. Then, |
\[a=\frac{P}{M+m}\] .. (i) |
Frictionless surface |
Draw the FBD of block and rope as shown in figure below. |
where, T is the required parameter (i.e., force) |
For block T = Ma |
\[\Rightarrow \] \[T=\frac{MP}{M+m}\] [from Eq. (i)] |
