The spring is initially in unstretched condition. It is first stretched by a length ' x ' and the work done is W₁. Then again it is stretched by further length ' x ' when the work done is W₂. The value of W₂ is given by (a) W₁ (b) 2W₁ (c) 3W₁ (d) 4W₁

Answer: (c). W₁ = 1/2kx². Total work to stretch by 2x: 1/2k(2x)² = 4W₁. W₂ = 4W₁ - W₁ = 3W₁ So the answer is (c) 3W₁.

The spring is initially in unstretched condition. It is first stretched by a length ' $x$ ' and the work done is $W_1$ . Then again it is stretched by further length ' $x$ ' when the work done is $W_2$ . The value of $W_2$ is given by

Show answer and solution

Answer: (c)

$W_1 = \frac{1}{2}kx^2$ .
Total work to stretch by $2x$ : $\frac{1}{2}k(2x)^2 = 4W_1$ .
$W_2 = 4W_1 - W_1 = 3W_1$
So the answer is (c) $3W_1$ .
