# Solution - 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 - HSC Science (Computer Science) 12th Board Exam - Physics

#### Question

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......

(a) W1=W2

(b) W1<W2

(c) W1>W2

(d) 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)

Is there an error in this question or solution?
