357684 A metal surface of threshold frequency \(10^{15} {~Hz}\) is illuminated by a light of frequency \(v\left(v>v_{0}\right)\). Most energetic electrons thus emitted enter normally in a magnetic field of intensity \(2.5 {~T}\). If the magnetic force acting on these electrons is \(10^{-8}\) dyne, then the difference between the frequency of incident radiation and the threshold frequency is \(4.3 \times 10^{{x}} {Hz}\). Find the value of \(x\).
