# Particle going on a field trip

**Electricity and Magnetism**Level 3

A unit postive charge of mass 2 kg was kept on point \((1,1)\). At time \(t=0\) an electric field was switched on such that potential \(V\) at any point \((x,y)\) is given by: \[V= {x}^{2}+y\] If the velocity with which it crosses the \(x\)-axis is in the form: \[\frac { \sqrt { \left( \beta { e }^{ \gamma }-\delta \right) } }{ { e }^{ \alpha } }\] Find \(\alpha\)+\(\beta\)+\(\gamma\)+\(\delta\).

**Clarification**: \(e\) denotes Euler's number, \(e \approx 2.71828\).
