Natie. Write your answers (with appropriate precision) in the blanks provided. I Indicate all units. 5. You use a string to rotate a 30-g cork. The other e and a 200-g mass is suspended at the bottom. This keeps the tension in the string c information to fill out the missing entries in the table nd of the string is threaded through a glass tube, onstant. Use this String | Radius | Theoretically! | RPM based on | Linear velocity| %error in Measured Tension (N) (cm) expected linear number of the v based on the linear velocity v rotations over 15 measurement measurement velocity seconds 41 29 18 20 50 120

Explanation / Answer

tension = m g = 0.200 x9.8 = 1.96 N  

tension will be 1.96 for all the cases.

and T = m v^2 /2 = 0.030 v^2 / r

v = sqrt(1.96 r / 0.030 )

r = 0.20 m , v =3.61 m/s

r = 0.50 m , v = 5.71 m/s

r = 1.20 m , v = 8.85 m/s
