Radius of circular path is given by

r = mv/qB

SO

v = rB(q/m)

v = 0.45*1.2*4.8*10^-11m/s

v = 2.6*10^-11 m/s

Four long co-axial thin walled cylindrical conductor A, B, C and D have radii R. 2R 3R and 4R respectively. A and C carry current I and 31 respectively to plane of paper on the other hand, B and D carry and 41 respectively outward to plane of paper. Then 21
