Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{10 \: N}}}}}

Step-by-step explanation:

Given,

Load distance ( LD ) = 2m

Load ( L ) = 800 N

Effort distance ( ED ) = 160 m

Effort ( E ) = ?

<u>Finding the Effort applied</u>

Apply the principal of simple machine :

\boxed{ \sf{L \times LD = E\times ED}}

\longrightarrow{ \sf{800  \times 2 = E \times 160}}

\longrightarrow{ \sf{1600 = 160 \: E}}

\longrightarrow{ \sf{160E = 1600}}

\longrightarrow{ \sf{ \frac{160E}{160}  =  \frac{1600}{160} }}

\longrightarrow{ \sf{E = 10 \: \: newton}}

Effort applied = 10 N

Hope I helped!

Best regards! :D
