MCQ

Two springs of force constants K1 and K2 (K1> K2) are stretched by same force. If W1 and W2 be the work done stretching the springs then......

Options

  • W1=W2

  • W1<W2

  • W1>W2

  • W1=W2=0

Solution

W1<W2

F1 = K1x1 and F2 = K2x2

Force is same

∴ K1x1=K2x2

∴x1<x2  ........(K1>K2)

Work done, `W_1=1/2K_1x_1^2 and W_2=1/2K_2x_1^2`

∴W1<W2  .........(K1>K2 and x1<x2)
