1.	An electronand a proton are moving under the influence of mutual forces . In calculating the change in the kineticenergy of the system during motion , one ignores the magnetic force of one on another . This is , because
Answer» the TWO MAGNETIC FORCES are equal and opposite ,so they produce no net effect the magnetic forces do not WORK on each particle the magnetic forces do equal and opposite (but non -zero) work on each particle . the magnetic forces are necessarily negligible . Solution :When electron and proton are moving under influence of their mutual forces , the magnetic forces are perpendicular to tem hence work done by these forces is zero .
