Maximum kinetic energy of the positive ion in the cyclotron is
$\frac{{{q^2}B{r_0}}}{{2m}}$
$\frac{{q{B^2}{r_o}}}{{2m}}$
$\frac{{{q^2}{B^2}r_0^2}}{{2m}}$
$\frac{{qB{r_0}}}{{2{m^2}}}$
What is Lorentz force ? Write an expression for it
If an electron and a proton having same momenta enter perpendicular to a magnetic field, then
A proton beam is going from north to south and an electron beam is going from south to north. Neglecting the earth's magnetic field, the electron beam will deflected (Zero gravity)
A particle having a charge of $10.0\,\mu C$ and mass $1\,\mu g$ moves in a circle of radius $10\,cm$ under the influence of a magnetic field of induction $0.1\,T$. When the particle is at a point $P$, a uniform electric field is switched on so that the particle starts moving along the tangent with a uniform velocity. The electric field is......$V/m$
A charge particle projected with velocity $\vec v$ in uniform magnetic field ' $\vec B$ ' then for maximum magnetic force on it, which is correct
