If a spring of spring constant k stretched by a length x under tension T, the energy

If a spring of spring constant k stretched by a length x under tension T, the energy stored is

Options

(a) 2k/T²
(b) 2T²/k
(c) T²/2k
(d) 2T/k²

Correct Answer:

T²/2k

Explanation:

Energy stored in the spring, U = (1/2).kx²
Since T = kx, .·. U = (1/2) k (T/k)² = T²/2k.
