Two particles A and B are revolving with constant angular velocity on two concentric circles of radius 1m and 2m respectively as shown in figure. The positions of the particles at t = 0 are shown in figure. The positions of the particles at t=0 are shown in figure. if m_(A)=2kg, m_(B)= 1kg and vec(P)_(A) and vec(P)_(B) are linear momentum of the particle then what is the maximum value of |vec(P)_(A)+vec(P)_(B)| in kg-m/sec in subsequent motion of two particles.

Magnetic force on a charged particle is given by vec F_(m) = q(vec(v) xx vec(B)) and electrostatic force vec F_(e) = q vec (E) . A particle having charge q = 1C and mass 1 kg is released from rest at origin. There are electric and magnetic field given by vec(E) = (10 hat(i)) N//C for x = 1.8 m and vec(B) = -(5 hat(k)) T for 1.8 m le x le 2.4 m A screen is placed parallel to y-z plane at x = 3 m . Neglect gravity forces. The speed with which the particle will collide the screen is
