Questions
Two protons move parallel to each other keeping distance r between them, both moving with same velocity V, then the ratio of the electric and magnetic force of interaction between them is,
detailed solution
Correct option is A
Electric force, Fe=14πεoq1q2r2=14πεoq2r2 ..............(1)Magnetic force, Fm=qVB=qVμo4πVqr2 .................(2) (1)(2) gives, FeFm=C2V2 ∵C2=1μoε0Talk to our academic expert!
