Question

Which property is observed when a beam of charged particles is fired into a magnetic field? If the beam of charged particles is parallel to the magnetic field, no deflection will occur. The maximum deflection happens when the beam is perpendicular to the magnetic field. The magnitude of the magnetic deflecting force is directly proportional to the magnitude of the charge on each particle. The magnetic deflecting force is always perpendicular to the direction of travel of the charge and to the magnetic field. O All of the above Question 13 (1 point) Two of the same positive charges exist on a horizontal line. Where is the electric field equal to zero from these two charges? O Between the charges To the left of both charges The field will never be zero To the right of both charges

Answer 1

since we know that force on the charged particle due o magnetic field- F = q X Y = q VB sino where a ere q = charge on the particle v = velocity of the particle B = magnetic field O- angle between V and B directions. This force deflect the charged particles. when particles move parallel to magnetic field a will be zero. then sino =0 So F=ON and no deflection will occur. If to magnetic particles move perpendicular O= go Sin 90' = 1 (maximum) F- qUR (maximum) deflection will be maximum so This By above formula it is clear when q increases, the value of F also increas and vise verna. so f is directly proportional to charge on particle (9). I since i and B have cross product so resultant vector direction will be perpendiculas to I both of and B, and this vector is the force vector. so option (e) is right option : ① All of the above

I since electric field due to point Charge - E =kQ मर where k= constant Q = charge on point charge. M = distance from the point change let zero electric fieltric field pointe is er distance far away from finst charge and a distance far away from second charge. since electric field is zero on point p. so ko ka >> M = 41, So zero electric field point will be at mid position between both positive changes so option (a) is right option between the charges.
