Physics - Electrostatics Question with Solution | TestHub

A charge particle is moving along electric field as shown in figure. What is horizontal displacement of the charge particle when it descends a distance of $y$ meter? Given $Q/m=9.6\times 10^7\mathrm{C}/\mathrm{kg},E=5\times 10^5\mathrm{V}/\mathrm{m}$, $y=84\mathrm{cm},g=10\mathrm{m}/{\mathrm{s}}^2$
