A spring of spring constant 5 × × 10 3 N/m is stretched initially by 5 cm from the unstretched position. Then the work required to stretch it further by another 5 cm is
Text Solution
Verified by ExpertsThe correct answer is:
C
$W = \frac{1}{2}k(x_2^2 - x_1^2) = \frac{1}{2} \times 5 \times 10^3 (10^2 - 5^2) \times 10^{-4}$
= 18.75 J
