P. 4679. A small object of mass $\displaystyle m$ and of charge $\displaystyle q$ slides down frictionlessly along a slope of angle of elevation $\displaystyle \alpha$ from a height of $\displaystyle h$. From the midpoint of the slope, it enters into a region of uniform horizontal electric field, and it decelerates and stops at the bottom of the slope. Determine the magnitude of the electric field strength $\displaystyle E$.
