Column I	Column II
A. Final kinetic energy	I. 120 J
B. Work done by conservative forces	II. -240 J
C. Total work done	III. -120 J
D. Work done by external forces	IV. 128 J

Choose the correct answer from the options given below

A-IV, B-III, C-II, D-I

A-I, B-II, C-III, D-IV

A-III, B-I, C-IV, D-II

A-IV, B-II, C-I, D-III

Text Solution

Verified by Experts

The correct answer is:

Area of graph

Total work done by all the forces
Hence,
Work done by conservative forces
Work done by external forces
Total work done - Work done by conservative forces
