An electron travelling horizontally at 1.5 × 107 m s-1 enters a region where it experiences a constant vertical acceleration of 3.0 × 1014 m s-2.
What is the horizontal distance the electron has travelled in this region when its vertical displacement is 6.0 × 10-2 m?
0.3 m0.3\text{ m}0.3 m
0.15 m0.15\text{ m}0.15 m
2.0×10−8 m2.0 \times 10^{-8}\text{ m}2.0×10−8 m
0.45 m0.45\text{ m}0.45 m
