Assertion : Graph between potential energy of a spring versus the extension `//` compression `(x)` of the string is a straight ling.
Reason : This is because potential energy is directly proportional to `x`.

Options

A. If both, Assertion and Reason are true and Reason is correct explantion of Assertion.
B. If both, Assertion and Reason are true but Reason is not a correct explanation of the Assertion.
C. If Assertion is true but the Reason is false.
D. If both, Assertion and Reason are false.

Answer

D

Explanation

`P.E.` of a spring, `U=(1)/(2) Kx^(2)`
`:. U prop x^(2)`.
The graph between `U` and `x` is a parabola. Choice `(d)` is correct.
