A body is displaced from x=4x = 4 m to x=2x = 2 m along the xx-axis. For the forces mentioned in Column I, match the corresponding work done is Column II.
Column IColumn II
(a) F=4i^\mathbf{F} = 4\hat{i}(p) positive
(b) F=(4i^−4j^)\mathbf{F} = (4\hat{i} - 4\hat{j})(q) negative
(c) F=−4i^\mathbf{F} = -4\hat{i}(r) zero
(d) F=(−4i^−4j^)\mathbf{F} = (-4\hat{i} - 4\hat{j})(s) W=8 W = 8 units
