Neco 2020 Agricultural Science Question 50
Practice objective / multiple choice question 50 from the 2020 Neco Agricultural Science examination.
A hand‑operated seed drill uses a uniform lever that is \(1.2\) m long and is pivoted \(0.3\) m from the handle end. The farmer applies a downward force of \(300\) N at the handle. The seed hopper, attached at the opposite end of the lever, weighs \(80\) N and must be lifted vertically. Assuming static equilibrium and neglecting friction, what upward force (in newtons) is exerted on the hopper? Is the hopper lifted off the ground?
