[Class 10 Physics] Work, Power, Energy
I’m confused on what the question even means. The graph I drew at the bottom was what I thought it meant (distance in x-axis and force in y-axis). To find work done, we’d have to find area right? So I did that and the total work done came to be 20 J. But that’s wrong(?)
Then I tried to approach it without graph (images 2 and 3) because I thought cos theta would make things easier. But eventually realised it was wrong because Force is variable, not constant.
I can’t find any reliable answers with AI or Google because everything tells me a different answer with their own logics
Can someone please explain how this question must be solved?
