Problem

Two singly charged ions, A and B, enter the space between identical horizontal capacitor plates with the same horizontal speed

v_0

. The plates are 5.0 cm long, separated by 6.0 mm, and produce a uniform upward electric field of

2.0\times10^{4}\,\text{N/C}

. Ion A has mass

2.0\times10^{-26}\,\text{kg}

; ion B has mass

5.0\times10^{-26}\,\text{kg}

. Both ions start midway between the plates. Determine the ratio

\dfrac{y_A}{y_B}

of their vertical deflections upon leaving the plates.
