Question

I have been working on this problem for a while what is the correct way to solve this?

**Original Question**

**Thomson Charge to Mass**

Suppose we have an electron moving perpendicular to a B-field along a circular path of radius 17 cm. If imposition of an E-field of 17.8 kV/m makes the path straight, what is the value of B?

\[ B\text{field} = \underline{\hspace{2cm}} \]

**Error Analysis**

Suppose our E-field measurement has an uncertainty of 0.25 kV/m and our radius of curvature measurement has an uncertainty of 0.6 cm. What is the total uncertainty associated with the magnetic field we just calculated?

\[ dB\text{tot} = \underline{\hspace{2cm}} \]
