JEE Main 26 June 2022, Shift 2, Physics Q33

Question 33 of 90 in this shift, Physics question 3 of 30, Section A.

Arrange the four graphs in descending order of total work done; where

W_1,W_2,W_3

and

W_4

are the work done corresponding to figure a, b, c and d respectively.

The figure, in words

Four F versus x graphs, each with axes F (marked F and -F) and x. Figure-a: straight line rising from -F at x=0 through zero at x0 up to F at x1 (dashed vertical at x1). Figure-b: line rising from -F through zero at x0 to F at x1, then constant F up to x2 (dashed verticals at x1 and x2), ending there. Figure-c: line rising from -F through zero at x0 to F at x1, constant F until x2, then falling linearly down to zero on the x axis. Figure-d: line starting at F on the F axis falling through zero at x0 to -F at x1, vertical step, then constant -F from x1 to x2, then back to zero at x2, followed by a triangular spike rising to a peak and returning to zero at x3.
