a positively charged particle having a charge q1= 1Cand mass m1=40 gramsis revolving along a circle of radius R=40 cmswith velocity V1=5 m/sin a uniform magnetic field with the centre of the circle at the origin O of a 3-D system. At T=0, the particle was at (0, 0.4m, 0) and its velocity was directedalong the+ve x-direction. another particle having chargeq2=1C and mass m2=10 gramsmoving parallel to the +ve z-direction with velcity V2=40/(pi)m/s collides with the first particle and gets stuck to it.Neglecting gravitational and coulomb force calculate the x, y, z coordinates of the particle (combined) at t = (pi)/40 s.
