Question
(a) Find the charge on a baseball, thrown at 35.0 m/s perpendicular to the Earth’s $5.00 \times 10^{-5} \textrm{ T}$ field, that experiences a 1.00-N magnetic force. (b) What is unreasonable about this result? (c) Which assumption or premise is responsible?
1. $571 \textrm{ C}$
2. Such a large charge would repel itself off of such a small object. Typical static shocks involve $\approx 5 \textrm{ }\mu\textrm{C}$
3. The $1.00 \textrm{ N}$ force is very overstated.
