in the figure. two identical springs have unstretched lengths of 0.25 rn and spring constants of 300 Mm. The springs are attached to a small cube and stretched to a length 1'. of 0.36 in as in Figure A. An external force P pulls the cube a distance D = 0.020 m to the right and holds it there. {See Figure B.) The work done by the external force P in pulling the cube 0.020 rn is closest to which of the following? Figure A 9.1% (FLA... A 0.80 ] B 12 J 0.060 ] D 6.0] E 0.12J
