An α - particle travels in a circular path of radius 0.45 m in a magnitude field B = 1.2 Wb/m2 with a speed of 2.6 x 107 m/s. The period of revolution of the α - particle is:

The correct option is D (c) 1.1 x 10−7 sThe correct option is C.Given,Radius=0.45m,B=1.2wb/m2,speed=2.6×107m/sSo, Time period =2πrv2×227×0.452.6×1079.99.1×10−7s1.1×10−7s

An $α$ - particle travels in a circular path of radius 0.45 m in a magnitude field B = 1.2 Wb/ $m^{2}$ with a speed of 2.6 x $10^{7}$ m/s. The period of revolution of the $α$ - particle is:
