Answer:
![r=97.22x10^{3} m](https://tex.z-dn.net/?f=r%3D97.22x10%5E%7B3%7D%20m)
Explanation:
Using the angular formulas can determine the radius using both values neutron star and the the knowing star so
![L=I*w](https://tex.z-dn.net/?f=L%3DI%2Aw)
![L_{1}=I_{1}*w_{1}=L_{2}=I_{2}*w_{2}](https://tex.z-dn.net/?f=L_%7B1%7D%3DI_%7B1%7D%2Aw_%7B1%7D%3DL_%7B2%7D%3DI_%7B2%7D%2Aw_%7B2%7D)
![I_{1}*w_{1}=I_{2}*w_{2}](https://tex.z-dn.net/?f=I_%7B1%7D%2Aw_%7B1%7D%3DI_%7B2%7D%2Aw_%7B2%7D)
I=Inertia of the star
w=angular velocity
![I=\frac{2*m*r^{2}}{5}](https://tex.z-dn.net/?f=I%3D%5Cfrac%7B2%2Am%2Ar%5E%7B2%7D%7D%7B5%7D)
![w=\frac{2\pi}{t}](https://tex.z-dn.net/?f=w%3D%5Cfrac%7B2%5Cpi%7D%7Bt%7D)
Notice the angular velocity determinate by the time and the Inertia have the radius value so
![\frac{2}{5}*m*r_{sn}^{2}*\frac{2\pi }{t_{1}}=\frac{2}{5}*m*r_{s}^{2}*\frac{2\pi }{t_{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D%2Am%2Ar_%7Bsn%7D%5E%7B2%7D%2A%5Cfrac%7B2%5Cpi%20%7D%7Bt_%7B1%7D%7D%3D%5Cfrac%7B2%7D%7B5%7D%2Am%2Ar_%7Bs%7D%5E%7B2%7D%2A%5Cfrac%7B2%5Cpi%20%7D%7Bt_%7B2%7D%7D)

To find the Mass of an object, you need to apply division.
Since Resultant Force = Mass X Acceleration
To find mass,
Mass = Force / Acceleration

Answer:
The force required to begin to lift the pole from the end 'A' is 240 N
Explanation:
The given parameters for the pole AB are;
The length of the pole, l = 10.0 m
The weight of the pole, W = 600 N ↓
The distance of the center of gravity of the pole from the side 'A' = 4.0 m
Let '
' represent the force required to begin to lift the pole from the end 'A' and let a force applied in the upwards direction be positive
For equilibrium, the sum of moment about the point 'B' = 0, therefore, taking moment about 'B', we have
× 10.0 m - W × 4.0 m = 0
∴
× 10.0 m = W × 4.0 m = 600 N × 4.0 m
× 10.0 m = 600 N × 4.0 m
∴
= 600 N × 4.0 m/(10.0 m) = 240 N
The force required to begin to lift the pole from the end 'A',
= 240 N.
