## Question

###### (a) $\mathrm{A} 0.140$ -kg baseball, pitched at $40.0 \mathrm{m} / \mathrm{s}$ horizontally and perpendicular to the Earth's horizontal $5.00 \times 10^{-5} \mathrm{T}$ field, has a 100 -nC charge on it. What distance is it deflected from its path by the magnetic force, after traveling $30.0 \mathrm{m}$ horizontally? (b) Would you suggest this as a secret technique for a pitcher to throw curve balls?
