A particle in SHM has amplitude $A$ . At $x = A /2$ its force magnitude is $F$ , potential energy $U$ , speed $v$ and kinetic energy $K$ . Select the correct statement(s) at $x = A /4$ .

Options:(select one or more)

Answer:

A, B, C

Solution:

$F \propto x$ : halves. $U \propto x^{2}$ : a quarter. $v^{2} \propto A^{2} - x^{2}$ : $\frac{15/16}{3/4} = \frac{5}{4}$ . K.E. is $\frac{5}{4} K$ , not $0.8 K$ .
