Answer:
velocity of mass when it slides of will be 1.36 m/sec
So option (b) will be correct option.
Explanation:
We have given mass of the slits m = 75 gram = 0.075 kg
Radius r = 75 cm = 0.75 m
Coefficient of kinetic friction [tex]\mu =0.250[/tex]
Acceleration due to gravity [tex]g=9.8m/sec^2[/tex]
When the mass slides of
[tex]\frac{mv^2}{r}=\mu mg[/tex]
[tex]v=\sqrt{\mu rg}=\sqrt{0.250\times 0.75\times 9.8}=1.36m/sec[/tex]
So velocity of mass when it slides of will be 1.36 m/sec
So option (b) will be correct option.
