A) \[{{f}_{A}}>{{f}_{B}}>{{f}_{C}}>{{f}_{D}}\]
B) \[{{f}_{D}}>{{f}_{C}}>{{f}_{B}}>{{f}_{A}}\]
C) \[{{f}_{A}}>{{f}_{B}}>{{f}_{D}}>{{f}_{C}}\]
D) \[{{f}_{C}}>{{f}_{D}}>{{f}_{B}}>{{f}_{A}}\]
Correct Answer: D
Solution :
Since, F=ma for stone \[A,{{F}_{A}}=2m\] for stone \[B,{{F}_{B}}=3m\] for stone \[C,{{F}_{C}}=5m\] for stone \[D,{{F}_{D}}=4m\] Then descending order of force exerted on the ground \[{{f}_{C}}>{{f}_{D}}>{{f}_{B}}>{{f}_{A}}\]You need to login to perform this action.
