A beam of 5 keV $\alpha$-particles and a beam of 5 keV electrons are absorbed by a target. The two beams deliver equal amounts of energy to the target per second. If $\frac{\text{ mass of }\alpha \text{-particle }}{\text{ mass of electron }}=7.27\times 10^3$, what is the value of $\frac{\text{ pressure on target due to }\alpha \text{-particle }}{\text{ pressure on target due to electron }}$ ?
