A) \[\frac{3}{4}mgd\]
B) \[\frac{mgd}{8}\]
C) \[\frac{mgd}{4}\]
D) \[mgd\]
Correct Answer: C
Solution :
Work done \[W=\overrightarrow{F}\times \overrightarrow{s}\] \[=Fs\cos 0{}^\circ \] \[=mad\] \[(\because s=d)\] \[\frac{mgd}{4}\,\,\,\,\Rightarrow \,\,\,\,W=\frac{mgd}{4}\]You need to login to perform this action.
