Answer:
time period of oscillation is 0.31 seconds
Explanation:
we shall know the formula:
[tex]T = 2\pi \sqrt{\frac{m}{k} }[/tex] ......where m is mass and k is force constant.
change 200gm into kg, then it will be 0.2 kg
T = 2π√0.2÷80
T = 0.314 seconds
T = 0.31 seconds rounded to 2 decimal places.
