Answer:
C. [tex]6.9\times 10^2\ \text{N}[/tex]
Explanation:
[tex]\text{Supplied force}=2\times 10^2\ \text{N}[/tex]
M = Mechanical advantage = 3.43
Mechanical advantage is given by
[tex]M=\dfrac{\text{Weigh of crate}}{\text{Supplied force}}\\\Rightarrow \text{Weigh of crate}=M\times \text{Supplied force}\\\Rightarrow \text{Weigh of crate}=3.43\times 2\times 10^{2}\\\Rightarrow \text{Weigh of crate}=6.86\times 10^2\ \text{N}\approx 6.9\times 10^2\ \text{N}[/tex]
The weight of the crate is [tex]6.9\times 10^2\ \text{N}[/tex].
