Answer 2

Answer:

here is your answer Mark as brillant

Explanation:

Work done can be positive,negative or zero.

Work done is positive when applied force and displacement is in same direction.Hence figure (b) shows positive work done.

Work done is negative when applied force and displacement is in opposite direction.Hence figure (c) shows negative work done.

Work done is zero when applied force and displacement is perpendicular.Hence figure (a) shows positive work done.
