Given,
Mass of the object $(m) = 8\;kg$
Radius of the object $(r) = 2\;m$
Speed of the object $(v) = 6\;m/s$
Maximum tension $(T_{max}) = \;?$
Minimum tension $(T_{min}) = \;?$
We have,
$T_{max} = \frac{m\;v^2}{r} + m\;g = \frac{8 \; * \; 6^2}{2} + 8\;*\;10 = 224\;N$
∴ Maximum tension $(T_{max}) = \;224\;N$
$T_{min} = \frac{m\;v^2}{r} - m\;g = \frac{8 \; * \; 6^2}{2} - 8\;*\;10 = 64\;N$
∴ Minimum tension $(T_{min}) = \;64\;N$
