A particle of mass m goes counterclockwise around a square path ABCDA with vertices at A(-1,-1), B(1,-1), C(1,1) and D(-1,1) in a force, F = x (k x) x . Here, and k are positive constants. Consider the work done along the following paths: (i) A B (ii) B C (iii) A B C D (iv) A B C D A The work done is zero for
