A charge at rest is accelerated by a potential Venters a region where there is a uniform magnetic field perpendicular to the direction o f motion. The field deviates the trajectory of the particle which becomes an arc of circumference with radius R. If the potential Vis triple d (becomes 3 V), calculate the radius of the trajectory O 3R OR/√3 O√3R 9R
