A) Less than W
B) Equal to W
C) Greater than W
D) Data is insufficient
Correct Answer: C
Solution :
Here applied horizontal force F acts as normal reaction. For holding the block Force of friction = Weight of block \[f=W\]Þ \[\mu \,R=W\]Þ\[\mu \,F=W\] Þ \[F=\frac{W}{\mu }\] As \[\mu <1\] \[\therefore \ \ \ F>W\]You need to login to perform this action.
