In the Figure, Two Identical Ideal Massless Springs Have Unstretched

question 58

Multiple Choice

In the figure, two identical ideal massless springs have unstretched lengths of 0.25 m and spring constants of 700 N/m. The springs are attached to a small cube and stretched to a length L of 0.30 m 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 external force P, that holds the cube in place in Figure B, is closest to

• A) 28 N.
• B) 25 N.
• C) 21 N.
• D) 18 N.
• E) 14 N.
