Question

a block A,whose weight is 200 N ,is pulled up slowly on a slope of length 5 m by means of a constant force F(=150 N)as illustrated in figure (a)what is the work done by the force F in moving the block A ,5 m along the slope ?(b) by how much has the potential energy of the block A increased ?(c) account for the difference in work done by the force and the increase in potential energy of the block.

Answer 1

Dear student,

The first part of the question is rightly done by Geeth Madhur.
As for the second and third part, they cannot be done without the figure(missing in the question). To calculate potential energy we should know the height reached.
Kind post the question with the image.
