1a) mv/bq
(general formula by equating mv2/r=qvb
b) n-2@
c) arc in magnetic field=mvbqx n-2@
apply velocity=distance/time time= (mvbqx n-2@)/v
time= m(n-2@)/bq
d) replace - by + in b) and c) but a) remains same....

23write F = q(v x B)
find direction of force , and also write F = mv2/r
so u get the r . now draw the circle . and u will find the answers
23and yes, use te fact that velocity will be tangential or always _|_ to the radius of the circle . and by using some geometry, u can find the angle subtended by arc in terms of theta
