Question

Akhil has to lift a load of $800N$ onto a platform of $2m$ height. Instead, he pushes the load up a ramp $4m$ long. Find the force required to lift the load vertically up.

• A. $200N$
• B. $600N$
• C. $400N$
• D. $800N$

Answer 1

The correct option is D $800N$

The vertical force is the gravitational force means weight of the load.

According to question, the weight of load is $mg=800N$, this will be the required force to lift the load vertically.
