Three particles, an electron (e), a proton (p) and a helium atom (He) are moving in circular paths with constant speeds in the x−y plane in a region where a uniform magnetic field B exists along z-axis. The times taken by e,p and He inside the field to complete one revolution are t e ,t p and t He respectively. Then :
