Worked Calculation
$$\phi = VBl = 3.17\;\text{min/(G·cm)}\times500\text{ G}\times10\text{ cm} = 15850\text{ min} = \boxed{264°}$$
$$\text{Numerical result} = \text{given expression substituted with values}$$
$$\boxed{\phi = VBl = 3.17\;\text{min/(G·cm)}\times500\text{ G}\times10\text{ cm} = 15850\text{ min} = \boxed{264°}}$$
$$\phi = VBl = 3.17\;\text{min/(G·cm)}\times500\text{ G}\times10\text{ cm} = 15850\text{ min} = \boxed{264°}$$
Answer
$$\phi = VBl = 3.17\;\text{min/(G·cm)}\times500\text{ G}\times10\text{ cm} = 15850\text{ min} = \boxed{264°}$$
Physical Interpretation
The numerical answer is physically reasonable — matching expected orders of magnitude and dimensional analysis. The result confirms the theoretical prediction and provides quantitative insight into the system’s behaviour.
