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`.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» Correct Answer - D `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. |
