A spring of spring constant 5 × 10 3 N/m is stretched initially by 5cm from the unstretched position. Then the work required to stretch it further by another 5 cm is a) 12.50 N-m b) 18.75 N-m c) 25.00 N-m d) 6.25 N-m
Here, W=1/2k(x22-x12) = 1/2×5×103((10/100)2-(5/100)2) =1/2×5×103/104(100-25) =18.75JHence the work required to stretch the spring further by another 5cm is 18.75 N-mThanks and regards
Work done by spring=1/2k(x22-x12)K=5×103N/mX2=10×10-2mX1=5+10-2mW=1/2×5×103(100-25)10-4W=18.75N-m
Dear student,Please find the attached solution to your problem. W = 0.5k(x22 – x12) = 0.5 × 5 × 103((10/100)2 - (5/100)2) = 0.5 × 5 × 103/104 (100-25) =18.75 JHence the work required to stretch the spring further by another 5cm is b) 18.75 N-m Hope it helps.Thanks and regards,Kushagra
