Questions
An and a proton are moving in circular paths in the same uniform magnetic field with same kinetic energy. Then the ratio of magnetic moment due to the rotation of to that of proton is
detailed solution
Correct option is D
(4)12 mv2=K.E.=E ⇒ v=2EmAngular velocity ω=QBm∴ r=Radius of circular path=vω=mQB. 2Em = 2mE1QBi = Equivalent current due to the moving charge.=Qω2π=Q2B2πm∴ M=Magnetic dipole moment =πr2 × i=π×2EmQ2B2× Q2B2πm⇒ M=EB∴ MαMρ=1Talk to our academic expert!
