a linear harmonic oscillator of force constant 65 Newton per metre and aptitude 4 centimetre

Dear student,

According to law of conservation,
Total energy= K.E.+P.E.
K.E. is maximum when A=0 and minimum when A=A (where A is amplitude=4cm=0.04m)
k= force constant

So, all of these (option 4) is the answer
