A charged particle +q of mass m is placed at a distance d from another charged particle -2q of mass 2m in a uniform magnetic field $B$ as shown in the figure. If the particles are projected towards each other with same speed v. After how much time collision will happen. $[v = \frac{qBd}{m}]$

R = qB m v ​ ; R ′ = 2 qB 2 m v ​ = R R = d T = qB 2 πm ​ , time period will be same Particle will collide at 2 d ​ sin θ = 2 d d ​ = 2 1 ​ θ = 6 π ​ = ω t t = 12 T ​ = qB × 12 2 πm ​
