To lift a load of 100 n a distance of 1 m an effort of 25 n must be applied over an inclined plane of length 4 m. what must be done to lift the load 2 m, using the same effort? a) use an inclined plane of length 8 m. b) use an inclined plane of length 2 m. c) use an inclined plane of length 10 m. d) use an inclined plane of length 16 m.

Hello!

 

A: Use an inclined plane of length 8m

Explanation:

Since we are going to use the same effort (or work in this case) if we use 4m to lift the load a distance of 1 m. In order to lift the load 2 m, we need to multiply the distance by 2.



So, we have that to lift a 100N load a distance of 2m, we need to use an inclined plane of length 8m.

Have a good day!
