Vedclass · Answer

(a)

In given condition, if $r$ is radius of curved path travelled by changed particle.

Then,

$\sin 	heta \approx 	an 	heta=\frac{a}{r}$

or $\quad r=a \operatorname{cosec} 	heta \approx a \cot 	heta \quad \dots(i)$

Also, $\quad r=\frac{m v}{B q} \quad \dots(ii)$

Combining Eqs. $(i)$ and $(ii)$, we get

$v=\frac{q B}{m} a \cot 	heta$
