A) \[\frac{dgm}{2kh}\]
B) \[\frac{2dgm}{kh}\]
C) \[\frac{dgm}{kh}\]
D) \[\frac{3dgm}{2kh}\]
Correct Answer: B
Solution :
[b] Acceleration \[a=\frac{F}{2m}=\frac{kt}{2m}\] The force diagram of block B in reference frame attached to A is shown in figure. The normal force passes through left edge at the instant the block is about to topple. The block will be on verge of toppling when \[ma\frac{h}{2}=mg\frac{d}{2}\] \[m\frac{kt}{2m}\frac{h}{2}=mg\frac{d}{2}\] \[\therefore \,\,\,\,t=\frac{2dgm}{kh}\]You need to login to perform this action.
