When a body is moving vertically up with constant velocity, then match the following.
\begin{tabular}{|ll|c|}
\hline \multicolumn{1}{|c|}{ Column I } & \multicolumn{2}{c|}{ Column II } \\
\hline i. & Work done by lifting force is & a. negative \\
\hline ii. & Total work done by all the forces is & b. positive \\
\hline iii. & Work done by gravity & c. zero \\
\hline iv. & Work done by lifting force \( + \) work done by gravity force & d. higher positive \\
\hline
