A particle curves within the uniform magnetic field inside a bubble chamber represented below: U = 1.54x10' m/s |B =708 T radius of curvature = 4.52 mm 25. The charge-to-mass ratio of the particle is 2.08x10- C/kg 0 4 81*10* C/kg 4.81x10' C/kg 2.41x109 C/kg 26. This particle was released during a radioactive decay event. What type of particle is it? OBeta positive Beta negative Alpha particle Free neutron
