Answer:


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

Explanation:

Given,

Load distance ( LD ) = 2m

Load ( L ) = 800 N

Effort distance ( ED ) = 160 m

Effort ( E ) = ?

Finding the Effort applied

Apply the principal of simple machine :


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


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


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


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


\longrightarrow{ \sf{ (160E)/(160) = (1600)/(160) }}


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

Effort applied = 10 N

Hope I helped!

Best regards! :D
