question about magnetic field?
Lorentz force = q v B sin90 >> which will provide the requisite centripetal force to be in the orbit of radius (R)
q v B sin90 = mv^2 /R
bullet (at t=0) entered (B) along (+x) axis, and was tossed into circular path at t=0
R = m v / q B = 3.4*10^-3 * 160 /[13.5*10-9*5.0*10-5]
R = radius or orbit traversed by charged bullet = 8* 10^11 m
————–
circumference = 2*3.14 * R = 50.6* 10^11 meter
===============
bullet is a dot (which travelled 1000 meter) on an arc of this circle
its path was = along diameter
——————
Quarter the circumference covered by bullet >> R is the deflection (perpendiculat from DOT on diameter) from path
[50.6* 10^11 /4] meter=quarter causes deflection = 8* 10^11
1000 m will cause = [8* 10^11] *1000/ [50.6* 10^11 /4]
deflection = 632.4 meter
