Q. Statement I: The total energy of a particle performing simple harmonic motion could be negative. Statement II: Potential energy of a system could be magnetic.

Options

A. Statement I is true statement II is true, Statement II is a correct explanation for Statement I.
B. Statement I is true statement II is true, Statement II is NOT a correct explanation for Statement I.
C. Statement I is true, Statement II is false
D. Statement I is false, Statement II is true

Answer

A

Explanation

Total energy of the particle performing simple harmonic motion is `E=K+U=k_(max)+U_(min)`. K is always positive, while U could be `+ve`, `-ve` or zero. If `U_(min)` is `-ve` and its value is greater than `K_(max)` then E would be `-ve`.
